Pretty much every day, at least for a while. B cup breasts are quiet nice to have when I'm being a girl, not so nice when I have to be a guy. The swimming issue was a problem when I was a teen; but since then, I've always worn a shirt when I go swimming as a guy, I just blame it on having such fair skin that I'd burn to a crisp if I didn't wear one. So far, no questions asked. But that doesn't stop me from longing to wear the bikinis in the Venus swimwear catalogs.
