sex addictions contributed greatly to my divorce from my 1st husband. I was my husband's "first," (I took his virginity) but he was already addicted to porn. Which is the reason he married me---I had been a full-blown sex-addict (when I was acting out, I had sex with everyone-literally, and liked to experiment) and had already been sexually abused by different men, so he figured he could just act his fantasies out on me without any repocussions. One problem with that was he had rape fantasies. So he would start fights with me to have an excuse to beat the tar out of me, then force me to have sex. I eventaully picked up bar-hopping and cheated on him like crazy. Well, needless to say, we are no more.

But, anyway, I don't see any reason for you to stay with him.

p.s. trust me, if you marry him, you will end up more alone than you are rite now. It's easier to be alone from the start than to start something that will have a painful ending, and your ending up alone anyway.
