its none of your business mom, I started jerking it before I could even orgasm, he was born with it, unless your going to cut it off him you should leave him alone. Honestly you sound like a sketch ball for even needing to ask us, or an evangelist/born again, and no not a good christian bc a good christian would know that people play with themselves, and they don't go blind from it. And honesty your not doing your son justice if you expect him to be married before he bones up on a chick, you should expect him to not have one night stands, and care deeply about a girl before they hit the sack, marriage is a sham 75% of people who get married are fated for divorce in this terrible culture.
Now that I'm done hating on you for no apparent reason because I'm angry that I'm up so late not getting work done, I'll give you some good advice. Never and I mean NNNNEEEEVVVVEEERR let your son or daughter have a cpu all by themselves in there room, or even access to it after your in bed. No it doesn't matter if you have filtering software they will get around that. I have a massive porn addiction from my parents not being smart about that kind of stuff when I was young.
