What can people tell me about the long term effects? I'm not talking about diseases, I'm well aware of stuff like prep-time, lubrication, protection, etc. But I'm really worried about stuff I hear like anal cancer, muscle damage, etc. Basically stuff that will affect you later in life no matter what precautions you take at the given time. I'm also gay so if I were in a relationship it would be my primary form of sex, not something I try once a week. Thanks so much for any help you can provide.
