I must admit, I'm about to have a very unpopular viewpoint here, but bear with me
.
I was a virgin until I was 32, and the only reason I lost it at all was because I advertised myself online. Before that, I had tried usual dating, and then signed up for several internet dating sites.
There were a lot of attached men on there. And I mean, a lot. Some of them were honest - they wanted no strings fun for the excitement value, because their sex drive was higher than their other half could cope with, or they loved their partner, but the sex was boring.
So, in my experience, the majority of people (not just men, incidentally!) using dating sites are doing it to Swing.
Men are very different from women in the way they view sex, and I'm ashamed to admit that my BF and I came together through an affair. His partner threw him out without talking to him about it... which I now believe she truly regrets. He is extremely happy with me, but yes, he may cheat on me. I'll cope with that if it happens, and in the meantime keep him so exausted he won't have the energy to stray.
My immediate thoughts are this:
1. Tell your BF you've found him out.
2. Calmly ask him why. Under no circumstances start an argument, as he can use that to portray you as unreasonable. So be calm, understanding and the perfect GF in every way.
3. Listen to him. It may just be cybersex to get a naughty thrill, he may have needs he hasn't told you of which he hopes to get online, he may want to Swing. But make sure he can tell you this stuff to begin with. A relationship with secrets is a relationship with a massive problem.
4. If he's unhappy and wants to move on, then fair enough. Would you really want to be with someone who is no longer in love with you? If he still loves you, but needs some changes, you talk about it. For example, my BF likes food sex, but I'm OCD, so it really freaks me out to get stuff on the sheets. So, we compromised - I said I'd do it, if he did the washing up and mopped the kitchen floor. And yes, that is working.
5. If he wishes to stay with you, for god's sake take him to a sexual health clinic and get yourselves checked out. I don't care what he says - do it anyway. Better safe than sorry.
6. Find out his sex fantasies and fulfill them. However, don't be casual with this power - use it wisely, or he'll get overstimulated. Rationing is key.
You really need to talk with him. In my experience, most men are on dating sites for the danger value and cybersex, nothing else, and really, that's not so awful, is it?
