Dad is weird

My dad is weird, it's been some weeks since he is talking about sex and making sex jokes all the time.
It all started when he found my femboy pics before the end of the last year, and besides family discussions and shenanigans caused by that (I kind of still am a bit traumatized because of that whole week lol) my dad began to say that I should get a girlfriend and talk to girls in my school and telling me about how he used to make out with all the women in his school or some shit
Now, he makes constant sexual comments, jokes and other things I don't understand well. It makes me feel dirty. I mean no disrespect to my parents at all but he's a degenerate. I'm tired. He wasn't like this before, and those jokes make me really uncomfortable, it makes me remember that day where he found my pics and I don't want to remember this.

How do I make him stop?
