Condoms

Ok so my SO and I have both been having issues with pain after sex and we know it isn’t an STI bc we’ve both been tested. I’m almost 30 weeks pregnant and the issues started after I got pregnant, so I think it has to do with that. Anyway, long story short we’re going to try condoms and lube to see if that makes any difference but I want some recommendations bc neither of us are condoms fans lmao
