I wasn't able to be in any relationship for a very long time. I had only two important relationships with men, one lasted a year, and the second one that just ended recently three and a half (and I met him when I was 30). Besides that I had some short quasi-relationships, I've known couple of men, some of them caused me a lot of pain. That's about it.
I didn't talk to my T about my relationships with men in detail. Just a brief outline. It's quite a painful stuff, also embarrasing, and I wasn't ready to go there yet. So I don't know yet what was it that made me sort of immune to dating and having relationships with guys. Whatever opinion I may have about myself, I think it's not due to my appearance, attractiveness. It's something else.
if you don't mind sharing your stories here, please post them. I wonder if there is anybody who had similar issues.
