I kinda of the impression that you are freaking yourself out for nothing, which in turn, suppresses your sexual appetite.
As in, this isn't a problem except that you are making it one.
Chill. Relax. Don't have sex for a while. Go be goofy and don't think of it.
You do get horny (porn) and you have seen the doc so I assume you are a perfectly healthy, sexual young lady.
We aren't sex machines, as much as some people drill it into us that we maybe should be. It is totally normal to go a while with a boyfriend and not have sex at all.
Seriously.

It's hot to play without the knowing we're-going-to-end-up-in-bed-or-he-will-be-disappointed game.
Just my little >02.
