Ok, here we go. I don't have much relationship experience, because I do a bit of Crossdressing. I sort of envy it. Personally I don't see altogether too much wrong with crossdressing. I too would much rather wear soft and silky chick stuff than scratchy man clothes.
Some people are quite open about it, even.
Some people aren't comfortable unless they wear a couple or three shirts. Some people like pretty clothes. It doesn't make you any less of a person or a less valuable partner in a relationship. Granted, it might freak out some girls, but chances are if you find yourself in a relationship that progresses to the point of mutual secret sharing, you'll already know if the person will accept your hobby or not. If this is not something you're willing to give up then it is going to have to be something that the person you love must accept.
