I'm a 21 y. o. transmasculine person, and I'm read as male. I think I understand what you are talking about.
Before transitioning, I identified as a gay woman, and I presented as such for about two years after understanding that I was actually trans. In this period though, I was part of a community of queer women. Sometimes, these or other queer women showed interest in me. To me, this was a positive experience, but I think that can be explained by how society views masculin women. For a long time, I identified as butch, and I still feel connected to that term.
Growing up, I was treated as a freak because I was boyish, and i learnt that no one would love me for who I was. When the queer community actually told me that my masculinity was attractive, that was more affirming than anything else.
The years around my coming out, I had one girlfriend, and a few other girls I had sex with, all of witch knew me as a transman, but they all got to know me as presenting as a girl. Most of them were queer, one way or the other. In my head, though, I told myself that they were straight (if they themselves were doubting), or that it was the male-liking part of their bi-ness that made them like me.
I'm sorry if I am hijacking your post, and I do think that it's different to be transmasculine than transfeminine! But you asked for experiences, and these are some of mine. All in all, I definetely prefer being with people who know I'm trans, and respect me for it. Now that I am percieved as a cisman, I even prefer queer people, but that's another story.
