None of them wears speedo. They have long pants and long sleeves. Also those pics are old school as hell, like 80 idea or something, one has only dudes (ugly) face. Frankly they seem to me like dudes idea of what women should like, but if that happened to work on cover and those books were super succesfull then whatever. I checked modern romance covers and they seem to be sexier to me. So I am not all that much odd one out.

I am not saying that sexy dude wears full body outfit that covers him entirely. I am saying speedo is really not it and it is used here to play to fear of Americans of ... something speedo related. It is not example of "sexy", but of something I am supposed to find disgusting. (I dont. In here, speedo is perfectly normal for swimming.)
