In my early 30s, it is very easy to get laid. Problem is all girls assume I am type of the guy for LTR or marriage, so after a couple of months I have a talk where I have to explain that constant talk about future and kids is too much for me and that I feel pressured and have to bail. Sometimes I meet up with these girls after the breakup for sex, but they always hope for LTR anyways.

How to avoid this vibe without being an asshole? I love those women and don't want to hurt them, I enjoy their company and value we give to each other. I just don't want them to immediately put me into marriage box. How to clearly communicate that I don't want LTR and that we are enjoying each without putting too much expectations?
