I am not against it, but I would never get pregnant myself. If other guys want to, then they should! Everybody should be entitled to do what they want (within reason, of course.....) But I could never deal with being pregnant. I want children someday, but I want to adopt.
However, I am concerned that because some of the only ftms that are really in the news were "Pregnant Men," which I think could possibly make people think of trans men as nothing more but women. And that is a false opinion which could damage the guys' self esteem.
But overall, it's not for me to judge....
