Sling wearing girl friend

A question at Yahoo answers

Sling Shot bikini too much or too sexy for public? (pics)? Is it a problem i get erected?

Now i am 16 my gf the same age and ever since she ha sex she has been wearing a sling shot bikini( for those that do not know what it is click her the picture is not my GF just google search http://lib.store.yahoo.net/lib/wickedtem... and http://www.coldhardfootballfacts.com/Ima...

She is one of the hottet girls at school and has a flawless beach body ( my firends say thats why i date her but her personality is 75% of the reason) So anyway we got the beach all the time we both and recently she has worn this and everyone stares at her, adults in revulsion, boys just stare and girls look jealouse) Now anyway i have sex two time in private areas of the beach beacuse she might as well be naked.

Now i love this but is it too much for public keeping in mind she is 16 and attractive ( she has never cheated on me and most girls know we never break up, so she is not seeking attention, She has plainly ssaid that we should have more sex. Also my speedos move forward each time i see her like that, and she likes that but in public
