Wearing womens swimsuits should not be something to be afraid of – it is of course up to you what you wear. In reality of course, this is not the case, people look & sometimes snigger. Personally, I have never had any what you might call abuse, sure, some people have taken a second glance, but never any more. One-piece swimsuits and the wearing thereof is not new to men as some of these links will show!
