MY boyfriend wants to have....

gay sex with me!!! But what are the risks????

well the real question is how old are you and how old is he? You should ask him if he's had sex with anyone else, if so you should use a condom and lube or just lube if it's his first time too because there's no risk of STD or STI transmission. The only real risks besides that is tearing your ass up but that's easily avoided with plenty of lubricants and taking it slow. I'm presuming you're the one getting it up the butt however if it's him then all my advice is the other way around obviously.

A sore arse
