I posted earlier but have just read all the replies now, and (I'm not sure how to tag people) but Maid, your answer was like it was coming from my head.
I also completely disasociate love and sex - I'd love to experience sex with loads of different people, men and women, but not for a second do I think I'd fall in love with anybody else, I might fancy them a bit yes but I love my partner completely, and we have a brilliant sex life (maybe not so much now due to pregnancy).
Both my LTR's, I couldnt have loved them more. I feel connected, safe, and am not / was not in any doubts that I'd want to spend my life with them. Obviously with ex GF that didn't happen but that was for other reasons.
Ironically, I think ex GF had a grass is greener moment. I know she didn't sexually cheat but I've a feeling she got emotionally connected to another older woman. I wish she had been able to talk to me about it to be honest, although I'm very glad it ended as I wouldn't have met my current partner.
any of the intense crushes I've had during both my LTR's, I'm guessing has been lust as I've never really got to know them deeply, and neither would I want to.
Just because I haven't experienced being in love with more than one person at the same time doesn't mean I don't think it can happen, if you're both happy to be in a polyamourous relationship. I can easily understand sex with more than one person but love, I might struggle with.
I have a few friends / friends parents though who are in loving relationships with more than one person.
Anyway, I'm at work at the moment so I'd better get on with what I'm meant to be doing
