Bikini Bottoms

[Torchwatch]

Fabric is fabric, it has no sex, it can be made in any colour and printed in any pattern desired but it still has no sex.

Any smooth front bikini made from a stretch fabric (lycra, spandex etc) will accommodate either a male or female figure of the right body size range, although you may need a size larger to fit a man. A man's smooth front bikini may be designed with a wider crotch seam than a woman's as it has to stretch further to stop bits popping out but there are no other real differences.
Only when the front of the suit is made into a pouch by sewing the 2 sides along a curve are the suits definitely for a man.

Wear the suits that make you feel happy and confident, if they happen to be women's suits then enjoy them. Keep your eyes open for nice men's suits too when you are next thinking of buying new, you might find something you like.
