I'm no longer satisfied with my boyfriend. f21

I apologize for any formatting errors; I'm new to Reddit.

My boyfriend M20 and F21 have been together for around two or three years. and it's been fantastic. He's a lovely boy who also happens to be really attractive.

Although it's very nice that he moved nations to be with me, we're both quite young, and I've been thinking a lot about cheating on him.

The idea of cheating actually makes me sexy, even though I know it's terrible. I genuinely believe that I should try new things while I'm still young, but I also like him.

I'm not sure what to do, so any advice would be greatly appreciated. Thank you.
