In my opinion, I would think telling another guy would be easier. Guys lose their hair. Going bald is more common for males than females. So, I would guess your boyfriend would look at it as,"Hey,this might happen to me someday" and be more understanding. If your Boyfriend does give you a hard time about wearing then I would say to him he had better pray he does not lose any hair or even have any of his hair thin. Two can play that game if he wants to be a jerk about it. Only if your BF is really young would I guess it might be a problem and even then as he grows older and matures his attitude will more than likely change.

I agree with Paul. If ANYONE(male or female) has a problem with you wearing a Toplace then what else will they find fault with? When you get old and begin to get wrinkles? I would casually mention it and not make a big deal over it. Just my opinion.
