I (27m) really love my fiancee (29m). We have a great life and a lot of fun together. We are very compatible sexually, for the most part. I wish he was a bit more versatile in bed (I am like 95% a top, but every 2-3 month I want to bottom maybe once, and then I don't want to do it for another 2-3 months; he's a total bottom so I haven't bottomed since we got together), and also that we'd have sex a bit more often (we do 1-2/week; since he bottoms he says more than that would take a physical toll). However, other than that, we're really happy about our sex life. We actually started our relationship through a purely sexual relationship and truly progressed into a romantic one by being each others' comforts through the pandemic.

I have a huge fetish for random hookups. I really like taking someone's clothes off for the first time, seeing what they're like in bed, and then never speaking to them again. My ideal relationship is one where we are committed to each other romantically 100% but where we can occasionally hookup with someone outside our friend circle. It has nothing to do with my happiness or lack thereof at home; even if we had sex twice a day instead of twice a week, I'd still have a kink for hooking up with new people. We can also make a rule that we only do this when traveling alone. We are currently monogamous.

I am starting to think about raising this topic with him, as I am getting very antsy and am currently crushing on anything with a pulse really even as I am still happy with our sex life at home (I have never acted on it). I already expect it to be a really difficult conversation, but the twist is that he has history with cheating - his father wrecked the childhood home by cheating with multiple women. Does anyone have any advice for how I should bring this up - or maybe I just shouldn't?
