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.
