Sex before the Gynecologist...

So... I have to go see the gynecologist tomorrow and my boyfriend and I had sex the night before... we didn't use a condom (this is normal; he's sterile and I'm on the pill) I'm super nervous to go because I don't want her to get all up in there and find remaining semen... how can I get super clean all up in there and make an aweful experience less awkward...?? Please help. I don't wanna be judged for unprotected sex...
