Love isn't always "a many splendored thing"

Sexually transmitted infections (known as STIs for short) have been around in one form or another for thousands of years. As the name implies, these infections are most commonly spread through sexual contact, though infected women can pass them on to their babies during pregnancy or the birthing process.

Most STIs can be cured if caught in the early stages. However, almost all of them can have serious or even fatal consequences if left untreated.

* You could be at risk if the receiver has just topped someone else
** Very low risk.
*** Unprotected anal sex is a very high risk activity for a bottom, much more so than for a top. The risk of HIV transmission to a bottom during unprotected anal sex is 15 in 1,000 versus 3 in 10,000 from a bottom to a top.

Kissing, mutual masturbation, and frottage or dry humping are considered safer sex activities, with little to no risk of STI transmission.

Using latex condoms (male or female) significantly reduces the risk of contracting STIs during anal, vaginal and oral sex.

Washing hands and the genital area thoroughly before and after oral-anal sex reduces the risk of transmission of most of the listed STIs and conditions. Condom use reduces transmission risk even further.
