27.“From a straight guy’s perspective: Like a lot of the previous comments, there’s an element of the taboo involved in it. Anal isn’t quite as accepted in ‘mainstream’ sexual discussions yet, and as such remains a bit out of reach for many curious individuals. Having already done anal on occasion with my girlfriend, the taboo is still there but has been transferred from a ‘mysterious and unknown’ sort of taboo to a ‘so rare as to be mystical’ taboo. On the pleasure side of things, it provides a nice change in sensation from vaginal, oral, and manual stimulation. And while it may not provide as much physical pleasure, its infrequency offsets that since it’s not something you’re typically used to like one of the above three. Also, the intimacy factor can’t be overstated. Because it’s such a rare occurrence for most guys (myself included), it carries a lot of weight when your girlfriend/wife/FWB/etc. gives you the opportunity. It requires more trust and communication than regular sex, and oftentimes your SO is sacrificing some of their comfort (and possibly dignity) to give you pleasure. It’s honestly both thrilling and humbling.”

The term Greek love has long been used to refer to anal intercourse, and in modern times, "doing it the Greek way" is sometimes used as slang for anal sex.[104] Ancient Greeks accepted romantic or sexual relationships between males as a balanced sex life (having males and females as lovers), and they considered this "normal (as long as one partner was an adult and the other was aged between twelve and fifteen)".[105]

Spreading STIs. Infections and diseases that are shared during sexual intercourse — such as HIV, gonorrhea, chlamydia, and herpes — can be shared through anal sex. In fact, anal sex is the sexual behavior for transmitting and getting HIV for both men and women. People on the receiving end (or “the bottom”) of anal sex are more likely to become infected with HIV than the inserting partner (or “the top”).
