I have conditions when it comes to sex
Is it normal that I have specific things that I won't do during sex as a man.
They are minor things such as.
1. I can't have sex with my glasses on I don't know why I just can't get hard if I have them on.
2. I can't get hard when there are bright lights agian I don't know why but they have to be dim.
3. If I ate something I'm not able to perform well if at all.
Is this something that is common do people have their own conditions for sex?
