Most if the youth of this generation are mean - guys and gals.
You shouldn't be at the beach anyway since all the women there are just an inch of being naked and you are putting yourself in a situation of temptation. If you want to swim, go to a beach that is secluded but bring a friend with you in case something happens to you.
I think guys are still cute if they are a bit overweight. The only thing that would be a turn off for me would be a really skinny guy or a morbidly obese guy (like 400 lbs or more).
