Husbands past..?

Im not sure if anyone else has experienced something like this it’s pretty embarrassing to talk about, but my husband had a past of being sexual curious I guess I could say and I find myself being embarrassed by it. Like I’ve seen his old dating profiles and I’ve just found it odd the things he was posting about himself on said dating sites and he said some of the things were to get more attention to him but I’m just not sure honestly. Like I’m okay with being my with someone who’s bisexual but like it feels weird to be with someone who was willing to be a bottom although he says he never did stuff like that before but I just don’t know it makes me feel weird and uncomfortable because I like bisexual men but I feel like that kind of stuff is kinda feminine.

Tl;DR my husband had a past with sexual curiosity and he said some weird ish on dating websites he was on and it makes me feel weird and uncomfortable and he thinks it’s just in the past so there’s no reason to care but it makes me uncomfortable.
