Are you saying that people that masturbate are crazy? Or are you saying that him not having sex with Sofia is crazy? I have a news flash for you, people masturbate. As for wondering why he isn't fucking Sofia, it could be because she constantly turns him down, or it could simply be because she's not there right now.
This is assuming that she reads what goes on here. Just because other couples have seen this site in the past doesn't mean that they all have, or even read what goes on here even if they do find it. Also, it's "site", not "cite."
