My friend is getting married to his bride-to-be?

wrong statement. It isn't his body, it is hers to do with as she pleases. She may let him use it just like he lets her use his body but he is getting married and she isn't a possession. She is a human and a free spirit. If he won't have with her on their wedding night, then he is the one that is missing out on a very special time for the two of them. She is probably hoping that he will want to explore on their wedding night and get a little bit crazy, but then I guess she doesn't know him as well as she should.
