Trans girls appreciate the little things more. Like holding her hands in public for giving us the kiss in public or just buying us flowers. I think we just appreciate these little things more, because we never really had this when we were younger or when we were growing up, and now that we are able to be ourselves in a relationship, it just make it all the more meaningful.
Most guys generally consider it as an advantage that we cannot get pregnant. For obvious reasons I personally would love to be pregnant and be able to give birth to my own child, but unfortunately I'm not able to. A lot of guys consider the benefit because then there's no risk of an accident happening when date with trans women.
