Horny during fertile window.

It's getting so out of hand. I've been trying to do school work, but the only thing I've accomplished is masturbating and thinking about sex. How do you girls cope with this?

It hasn't always been this bad. I'm single, and I don't want to have sex unless I know, love, and perhaps want to marry that person, so a FWB is out of the question. Is there any other way to get these desires out of the way? It's horribly frustrating.
