That's a very good question, but I'd like to put it this way, from personal experience:
'Do you think MTF would accept you more if you were straight or gay/lesbian?'
Almost all MTF attending MTF meetings were and are into women (only) and are biological fathers to several children (sometimes with several ex wives)
There's actually so many of them that they're a majority and automatically assume I was/am into women too.
And was as masculine as they were/are too.
No matter how detailed I try to explain that I was always feminine to begin with and into men only; they just don't or can't believe that.
They seem to assume all MTF used to be straight, masculine men.
Which actually makes me feel like my background and history gets 'stolen' from me because of their denial.
The ones I get along fine with are their cis (ex)wives for the simple reason we can relate to eachother...because we are feminine by nature.
Those ex straight, (very) masculine MTF who think I was like them annoy me to such an extent that I quit attending MTF meetings.
I have no social or whatever problems in daily life while interacting with people/strangers...
Only with MTF, explaining myself over and over again that I'm not and never was into women..and sometimes trying to fend off being hit on, even AFTER explaining I'm NOT into women and the likes.
