Lovers, take heed. This is why photographing and/or recording yourself naked or any sexual deeds is just generally not a good idea.
OP, get a grip. By distributing that picture, several things could happen:
1) He is under 18, you get arrested for child porn offences. Enjoy prison, your fellow inmates will take you and a child porn offence and come up with a paedo.
2) He is not under 18, but you end up looking like the utter bitch he says you are.
3) He is not under 18, but you end up looking like a hero, and he hates you even more than he already does.
Judging by your attitude, he probably hates you for a very very good reason.
