Hi, am gay 24 years old. I have been in a relationship with my dude for almost 6 years now. I have been enjoying anal penetration until late last year whereby I started experience anal spasm and fissures more often. This happens exactly after engaging in sex. I don't seem to enjoy it the way I used to way back when we met. The sphincters seem to be tight for penetration to take place. What could be the problem?
