Alot of homosexuals has been molested when they were childrens and that's alone need to answer your question about leaving an homosexual near your childrens.
An homosexual told me he was abused when he was a child by an older child and as he was a mate in school I knew it was the reason why he became a homo. Another homosexual/bisexual/confused sexual and really disturbed person was my buddy, he was into necrophilia, the guy would really tell me alot about himself, probably things he will never tell to a psy. He was raped at 10 by an older guy and that's a reason for his bisexuality.
That last guy was confused about sexuality to some weird extent. I finally dug enough to know his fascination toward necrophilia. He was rejected alot of times by plenty of girls, in very humiliating ways sometimes because he was ugly and fat. One time he went to see a girl he used to talk to for like months or years, I don't remember, then when he went to see her she really didn't like him facially and he was shocked of the way she behaved toward him. So the guy went on a trip to meet her when they finally met in the train station, she talked to him a bit and told him " I'll be back" and never went back to see him but texted him " I have something to do, I really need to go". That's really heartbreaking. He told me that he roamed, like an idiot, for hours in the train station, then the city without her coming back or answering his calls. It's just fucking sad. So all of these experiences with girls made him go necrophilia because a death body doesn't reject and doesn't go away.
Great guy after all. He was fat and I was the one to introduce him to weight lifting ( As weird as he is, he took to another level especially when he dieted. He took it seriously, even told me he puked when he knew he fucked up.). Now he seems to doing fine, he is not fat anymore, he is not that ugly anymore but this shitty experiences will have to live with him forever.
