<human>: Could you distill the essence of the text into 1-3 sentences?

I am fairly protective of my girlfriend and sometimes overly jealous. She is currently picking out a bathing suit and it bothers me because I wouldn't want other guys looking at her in her underwear, and the suits she's considering reveal just as much, if not more. I hate that she'll be wearing practically nothing for anyone to see, but because it's a bathing suit and not underwear she gets indignant if I protest. Why are most girls so comfortable with running around nearly naked if it's in a beach environment? I admit my views on this are somewhat old fashioned, in that I feel that she shouldn't be showing much skin, but even so, I hate thinking of all those macho jackass guys that tend to frequent the beach ogling her and picturing her without the suit, which isn't so hard considering it's about one square foot of fabric. I realize that there is some amount of padding in the top and the bottom doesnt hug the skin as tightly as panties (in most cases), but there is still so little left to the imagination.
<bot>: if she would never wear underwear out in public why am I not allowed to be uncomfortable with my girlfriend wearing skimpy bikinis?
