My current gf has told me about a husband she had that liles to wear panties and about 3 boyfriends she has had that she caught sucking cock. She says she left them for this but sometimes i wonder if she turned them into sissies and would do the same to me. Wish i knew for sure. Mmmmmmm
Not every woman will accept a man that wear panties or sucks cock. You should speak with her and see what her actual position is on the topic, that is what I did with my current wife before we married, we talked to all out in advance.
