I sometimes wonder if some are just congenitally unable to realise that they'll always be judged on how they present themselves and how they behave.
If you think of your CollarMe profile as a first impression, it should be obvious that the content of that profile is always going to raise associations in people's minds.
A few simple rules of thumb. If you want someone to engage with you seriously - as opposed to using you as a cumslut - then:
* Avoid pictures of vagina. There's nothing interesting about something which everyone gets to see. It also tends to telegraph that vagina is the only thing you think you have to offer - some guys might enjoy chicks with low self-esteem, but they're generally not men with any degree of self-respect.
* Likewise with you chowing down on some guy's cock. We pretty much figure that if you're a grown woman, you've actually had sex at some time. We don't really need photographic evidence.
* Learn the difference between erotic and vulgar.
Of course, if you're into objectification, humiliation or being the centre of attention at BukkakeFest 2012, then knock yourself out. If not, consider the merits of a little subtlety. You'd be surprised at how effective it can be.
