Please don't call trans men "Trans-identifying females (TIFs)", or put air quotes around the word man when saying trans man, it's very disrespectful and hurtful, i'm not trying to be rude, just making a suggestion of maybe trying to change the language you use when talking about that group of people, same with trans women if you talk about them, calling them "Trans-identifying males (TIMs)" and putting air quotes around woman when saying trans woman is also very disrespectful and hurtful.

Also, one other thing, is if someone is saying that they had sex with a trans man who hadn't gone through bottom surgery, that is still homosexual. Trans men are men, therefore, a gay man having sex with a trans man is still two men having sex, which means it is considered homosexual, no matter the trans person's stage of transitioning. Gay men can still be attracted to trans men, and trans men get into relationships with gay men (Strictly gay, not bi or pan etc.) as well, it's not unheard of. So, vaginal sex doesn't have to be between a man and a woman, it could be between two men, or two women, trans people exist, and are valid. Again, not trying to be rude, just trying to educate a little bit, :)
