In a relationship but want to have sex with other people?

I'm 18. I'm in a good relationship right now. I've only had two very short-term partners before I met my current one and we have now been going out for 8 months. We moved in together in January (3 months after we had been going out) and all is going well.

However, recently I have been having these urges to have a sexual relationship (no strings) with somebody else. I have found myself flirting in chat rooms over the last week and talking to some people about meeting up.

I'm not sure if I could ever go through with it because I love my partner, but the urges are really strong and I'm thinking it is because I have not had many sexual experiences before my current partner. Because I am 18 I sometimes think that I have missed out on having fun and that I fell in love too early. However, I am certainly satisfied when having sex at the moment which adds to my confusion.

I have spoken to my partner about this and he seems to think it is because I don't love him. This simply isn't true. Could someone advise me on how to deal with these thoughts and what could be triggering them?

i love my wife, and we have an open marriage... we see other people... it works for us...

This is very normal. Dont worry. Be brave to have sex with whomever you feel like. Then one day you will stop once you are bored.

I can think of two things you can do, that wouldn't involve cheating on your partner.
1) Y'all can play dress up. He can act like different types of men (Cop, Plumper, Football player, etc).
2) Close your eyes and fantasize about anybody you want to while having sex with your boyfriend. (Just don't call out any names, that will surely make him mad)
