A little background, my bf and I have been together for 4-5 years now and I'm his first in pretty much everything. At the time, we decided to keep it "open" in theory in that he should be able to experiment with different guys. It would not be entirely fair for him to stay in a monogamous relationship with me at the age of 20 and only have sex with me.
Our sex life are okay I would say. He has more sex drive then I do, we are both top-ish even though we are versatile in practice. He tend to bottom more for me because he's thicker and it usually takes a long time until I'm comfortable with him inside of me. (so I suppose there's some problem here)
However just yesterday he brought up the issue and he's seeing how I feel about it (we agreed to be totally honest with each other)
... but at this point, I'm very much emotionally invested in him and find it very hard to imagine him with another person. (and the insecurity and all that fun stuff)
I am a few years older than him but I was never the kind to do one night stand so I don't even have a point of reference really.
Now that we talked/argued a little, he said that he'll respect my wishes and that he still loves me and won't do anything to hurt me. However the issue will just keep coming back up and before long the resentment will be there and it won't be pretty later on.
Besides, he's 24 now, if he doesn't go and fool around now when he's still young and good looking when would he actually do it?
Is there anyone with a bit of experience in this matter or some suggestions? I don't know what to feel right now really.
