I've got pretty full lips myself but I actually find it one of my more attractive features. I love guys who have kissable lips. But on a side note, my therapist told me that my T might actually thin them out so that may happen for you.

My boyfriend is biologically male and he has full, gorgeous lips. Nice and pink too. My brother is also biologically male, and he has my exact same full, rosy lips I have. We inherited them from our biological father, along with our long eyelashes XP. They're some of the only things that I'm glad I got from him. I'm actually scared that I'll lose my lips from hormone therapy. Dear God, I hope I don't lose them @_@. So yeah, don't worry about your lips. You should be fine regarding your lips. If it still continues to bother you...facial hair? I have no idea how to hide these things XP.

I actually like Women, but men with bigger lips are pretty awesome actually, but I guess it varies for everyone

Mine are pretty thin, the odd thing is I got ermmm let's say questioned on the street a few days ago. One of the things they said, that took me by surprise was 'if you're a boy, then why are your lips so small' and I was like... huh?

I would like to echo everyone else and tell you I've seen plenty of men with really full lips. My partner is one of them! He has wonderful cupid-bow lips (top lip is a bit thin but the bottom lip is very full and almost pouty) and they are a bit pink.

I'm sorry that this probably won't help you feel better about your lips It's very difficult to minimize lips as they are usually much more easily maximized.

Makeup is probably not something you'd like to do anyways and I can't imagine having some kind of concealer or foundation on them A pale skin-tone lipstick would only make them shiny and draw more attention to them as well

You can get lip reduction surgery. I think the only non surgical way to thin your lips is smoking. Part of that is just the action so you could take up smoking e cigs and drinking with straws. Supposedly certain ingredients in chap sticks can lighten your lips.
