First of all, Louis's comment is actually on topic and a good question.
Most people do have "Fetishes" - that is an erotic/sexual fascination with material objects that are related to the male/female body in one way or another and as long as you're not illegally exploiting or endangering anyone, there's nothing to be ashamed about.
I came from a "conservative" family and their thoughts about sexuality were quite restrictive and very prudish to say the least. When I was an early teenager (in the 1960s and 70s), my erotic and sexual thoughts were "All over the road" (both Str8 and Gay) and I was very confused about the true future of my sexuality.
I recall my fascination with taking swimming/W-Polo in my high school P.E. class and I would often J.O. in bed while thinking about being in the pool with 20 other guys almost naked. Despite the pleasurable thoughts and sensations, I was also very uncomfortable with my J.O. to those fanatsies.
However since the internet came along, I was able to share and explore my ideas with others and I now consider myself to be "normal" with regard to my place on the sexuality spectrum.
Getting back on topic, speedos and bikinis have always been at the top of the list of Gay and Str8 fetishes.
Here's a list of my horniest fetishes in order of preference:
Swimming or playing W-Polo in the nude
Swimming or playing W-polo in a speedo
Japanese (in the nude) communal baths or hot tubs
Feet, legs, butts, navels, nipples, necks
Short athletic shorts, tees, and sneakers
Jeans, tees, and sneakers
And possibly something else I haven't discovered yet!!!
