So, if there's no opportunity, then what? Self-control level is irrelevant if there are no willing members of the other sex.
That is true, to a point. So are you saying that if there was a willing member of the other sex, you'd jump on it just because it's there? then you prove that you don't have self-control. Circumstances can make you celibate involuntarily, but the test is when circumstances do not prevent you from having the opportunity. It's a little thing called "character".
Believe me, I know that it's slim pickings. There are an awful lot of truly messed up women out there, an awful lot who say they want a good man, but won't take him when they have him. Same way for women. Real men are few and far between.
