Not sure of a good place to ask this question

Just started dating a girl where there’s mutual attraction both sides, seems like it has potential. Every time I think about her I get a raging boner, that’ll often subside until I think about her again and then it comes back. It’s gotten to the point where it’s annoying me just hanging around the apartment.

Tips for handling this? Clothes for handling this? like I said no clue who to ask for help on this
