I've always felt that my boyfriend of 3 years have a great relationship - no major arguments and a great sex life.

Then recently I found out that my boyfriend had been having webcam cybersex with guys online behind my back for the past 6 months using a software program called CAM4 (I've never even heard of this program before)

This is what he says:

1). He has never physically cheated on me or never met with anyone he chatted with.

2). He has not been on any dating/hookup sites like manhunt, A4A etc.

3). He does have urges to be with other guys, but currently he does not want an open relationship.

4). He is sorry for doing this behind my back and says that the cybersex is an "safe" outlet for his sexual urges.

I believe what he is telling me. But again I feel hurt, betrayed and confused.

Am I making a big deal out of this? Is my insecurity warranted? Do you think cybersex is a healthy way to safely purge your sexual urges? Or does it lead to temptation and eventual cheating? What should be a realistic expectation?

I don't know if I can or should tell him to stop this behavior. Any advice would be greatly appreciated. Thank you.
