Honestly, I think you need to expand your social circle. Not saying you should completely get rid of these people as friends - if you truly think they treat you well and respect you, and it's not just toxic friendships - just get out there and try to find others who you are more aligned with and can discuss more with. People outgrow each other and that's okay. I think it's alright for your friends to talk about boys and their hook ups but I think it's a red flag for them to incite you into doing the same when you are happy in a committed relationship. Different strokes for different folks. Don't let anyone pressure you into thinking you should be going out and having wild one night stands when you don't want to. It's okay to do that, but if you don't want to do that, it's perfectly fine too. And if they are truly your friends, let them know you aren't interested in that and you don't appreciate being made fun of for it. Nobody should be making fun of others for their relationships/sex life. And again, if they are truly your friends, they will understand and hopefully apologize and back off and see how it's wrong. Women shouldn't tear other women down for their choices!

For advice on the meaningful conversations bit: is it possible to do stuff that...ignites meaningful conversations? Do you guys have shared hobbies? It's easy to get stuck in that rut of getting together for a glass of wine and Netflix kind of night. You could try suggesting things like visiting a museum or an art gallery, seeing a movie, playing badminton, going for a hike or sightseeing, etc. I know it's difficult with the pandemic of course. But maybe involving some of your hobbies, whatever they are, will stimulate conversation around those interests rather than just boys.
