Sexually mmfed

Julia • Livin in the beautiful state of Virginia!
I haven't had sex in about a year now, and the last time I had sex is was very unpleasant and disappointing. 
I've looked around tinder and really wouldn't mind hooking up with some guys/girls in my area but I'm pretty self conscious and I'm worried that they wouldn't find me as attractive in person?? Idk. 
Any advice for a sexually frustrated, insecure single lady?
