So, are you saying that this mod was basically "on the down low" until age 25, having girlfriends while sleeping and sucking off men on the side, potentially risking his girlfriend's health from HIV or other STDs by being a lying, cheating pervert? 
Who knows what he did.
I know a guy (quite big on certain BBing boards) who for decades was hooking up and fucking guys without a condom. This despite the fact he had a wife and kids. As far as i know, he never passed anything on to his wife. This guy was bisexual though. He was also fucking hookers in Thailand/Vietnam/Indonesia/Philippines without a condom too. To say he thinks with his dick would be an understatement.
It appears with OMR that he didn't 'come out' until later on in life because of his strict upbringing. I guess he got to a point where he decided he was unhappy conforming to what was expected and at that point he followed his feelings... People will often conform to what is expected of them until it becomes too painful to continue.
I feel that I always had the desire to be gay (even if subconsciously at first), but that physiologically, my body wasn't boxed into the stereotypical presentation that one would have when assuming a gay preference. You could blame it on the fact that while growing up, I had no choice but to be straight due to my strict upbringing, faith and lack of other gay/lesbian individuals to open my eyes to another reality.
The "physiologically" stuff is a bit of self-denial. There is no "stereotypical physiological presentation" of gayness. He just didn't have the guts to come out until later on in life. That is nothing to be ashamed about this, many gays end up fucked up in the head because their upbringing specifically drums into them that gay=bad.
