Bridezilla?

My boyfriend's brother is getting married in July and my bf has been appointed the best man. According to wedding "laws" it is his job to plan out the bachelor party. Hanging up with his bro after discussing the plan and guest list for the party my bf receives a call from his close to crying sister-in-law-to-be. She tearfully requests that he not have a stripper at the party because she finds it disrespectful and it "grosses her out." After he hangs up with her me and his mother immediately tell him that he MUST have a stripper there now.. but that's besides the point.
Why is it that some women get so hot and bothered over their soon-to-be-husband watching a naked girl dance? Is it a trust issue? or is it just that maybe they do find it "icky"? Whatever the case maybe it is only a body; a dancing, naked body. Its presence at a bachelor party is only to represent that freedom that is being taken away from the man right? If you truly beleive that the man you are going to be marrying is the right person for you than the fact that he is going to be looking upon another body shouldn't be an issue. He is not allowed to touch the body in front of him plus he is going to be spending the rest of his life with you (if we beleive in traditional views of marriage... if not that's okay too).
If she feels the need to assert so much control over his sight, and thus over his body, I feel bad for that soon-to-be marriage.
