Sex with a new partner

Chill out
Calm down now. Performance anxiety isn't pretty, and it takes all the fun out of sex. In fact, too much anxiety might end up meaning there's no performance at all, if you get the drift. Take it easy, and lower your expectations. First-time sex with a new partner is more about exploring each other's bodies and getting to know them better, rather than putting on a show and trying too hard to impress.
Take your time
What worked brilliantly with a previous sexual partner may not work now, but that's no reflection on your prowess as a lover. Different people respond to different things, and finding out what can be half of the fun. Nerves can get in the way too, and sometimes it takes a while before someone can get naked and relax. If either of you are feeling too stressed, just take the pressure off; you don't need to have sex there and then. Wait until you're both sure that you're ready. If you've decided to go back to yours, and sex is on the cards, then a little preparation goes a long way. Make them feel special and comfortable. Tidy up a bit, have something good in the fridge for breakfast, and stock up on their favourite drink. Oh, and make sure you've got enough condoms, because running down to the late night garage with a hard-on or a hitched-up skirt is not a good look, and it kind of breaks up the mood.
If you're going back to their place, be a good guest. Don't make an automatic assumption that they want to have sex with you, and take your own condoms as well, just in case. You'll get extra points for turning up on time, looking and smelling good. Let them know you're having a good time and like their company.
Have a laugh
It's only perfect in the movies. Nobody's psychic. You have to tell one another what you like and want, and if you're not enjoying something then don't be scared to ask for something different instead. If you are pulling out all of the stops to please your new partner, make sure they make an effort to do something pleasurable for you too - there should be some give and take. Keep a sense of humour at all times, and if you fall out of bed or get cramp in your toes then laugh it off instead of getting embarrassed or worried. Even if you cringe at the time, it could be something you both look back on later with a warm fuzzy glow. "Remember the time when we. . .?"

Sex and drugs

LSD/ Magic mushrooms
High: Some users report an increased sexual awareness while tripping.Low: Trips are unpredictable. Hallucinating unpleasantly during sex could be traumatic, while a heavy dose may leave users totally turned off.
Cocaine
High: Cocaine is a stimulant drug. In small doses it can increase sexual arousal and make orgasms and erections easier. Low: In larger amounts, cocaine can still fuel sexual desire, while decreasing the ability to actually perform properly. Problems achieving erection and orgasm are very common.
Amphetamines (speed)
High: The initial rush may lift the libido, but the feeling is unlikely to last.Low: Male users may find the penis is less sensitive or responsive, and ejaculation difficult to achieve. As a result, sex can last a long time - which places both partners at risk of chafing (rubbed raw skin). Painfully funny on paper. Pure pain, in reality.
Cannabis
High: Users can feel less inhibited and unfriendly, while the increased sensory perception can turn stoners all touchy-feely.Low: Blokes on dope risk a reduction in testosterone production, and a drop in sperm count, while females may experience some fertility problems due to changes in ovulation and menstrual cycles.
Ecstasy
High: An increased sense of warmth and empathy towards sexual partner. Some users feel they are more physically aroused, (although others report a loss of sensation and delayed orgasm).Low: Increases the chances of risky sexual behaviour. A recent study showed users were more likely not to bother using condoms or other forms of contraception. Also, the drug-induced sense of loving everyone around you could mean you wind up sleeping with someone you don't really like at all.
Opiates
High: Drugs such as heroin, morphine and codeine belong to a drug group called opiates, which have a painkilling, detached effect. Codeine, in particular, is a feature in some strong over-the-counter painkilling products, so about the only appeal there, sex-wise, is that headaches won't wash as an excuse.Low: Opiate misuse can lead to full time problems such as impotence, lowered libido and difficulty attaining orgasm.
Poppers (alkyl nitrites)
High: Some users take poppers during sex because they enjoy the brief, intense head rush and relaxant effect. Particularly popular among gay men.Low: Alkyl nitrites reduce blood pressure. This means Viagra users should steer clear as the combination could be fatal.
The potential effect of a drug on sex is just one of many factors to consider before taking any substance. Knowledge is power, so get wise to the risks involved right.

Teens and Sex

Why teens start having sex in the first place. Environment, age of partner and perceived family support may affect young people's decisions to have sex.

While the media bombards us with alarming statistics about the number of teenagers having sex, few reports shed light on what might encourage teens to become sexually active in the first place. Three studies offer some insight into sexually active teens: environment, age of partner and perceived family support may affect young people's decisions to have sex.
In a study presented at a meeting of the American Public Health Association (APHA), researchers at the University of Kentucky followed 950 teenagers at 17 high schools in Kentucky and Ohio from 9th to 11th grades. They found evidence that teens who have intercourse tend to think their friends are too, even if they're not. "You're 2.5 times more likely to have sex by the 9th grade if you think your friends are having sex -- whether or not they really are," says Katharine Atwood, assistant professor at the Kentucky School of Public Health. Plus, teens tended to overestimate how many of their friends were sexually active. Only 33 percent of kids in the study had had sex by the 9th grade, but 31 percent said that most or all of their friends had had sex. "If you can persuade them that fewer are having sex than they think," she says, "that can have a significant impact on their behavior."
Among young girls, a partner's age is a risk factor for sexual activity. "The younger the girl is at the age of first intercourse, the more likely she is to have a much older partner," says Harold Leitenberg, Ph.D., a professor of psychology at the University of Vermont. His study, published in the Archives of Sexual Behavior, found that of 4,201 girls in 8th through 12th grades, those who lost their virginity between ages 11 and 12 tended to have partners five or more years older. For girls who had sex later in adolescence, the partner's age disparity was much smaller. Early sexual initiation was also associated with a number of behavioral problems. "Ignoring the age of the partners, the earlier a girl was when she first had intercourse, the greater her risk of suicide attempts, alcohol use, drug abuse, truancy and pregnancy," Leitenberg says.
The good news is that while teen sex may not be wholly preventable, the health risks it involves can be reduced through communication within the family. More research presented at the APHA meeting showed that frequent parent-child discussions about sex and its dangers may prevent teenagers from engaging in risky sexual behavior. Researchers at Emory University questioned 522 sexually active African-American adolescents about the openness and support that their families provided. Adolescents who felt that their families were more supportive were less likely to have unprotected sex, and thus were at a lesser risk for pregnancy and disease.
