If you have a girlfriend are you constantly having sexual thoughts about her through out the day?

This is not so much a question, more of an inquiry. I’m a woman. I’ve always been curious about how men think about these things. Of course I really like my boyfriend for who he is, but sometimes I cannot get those thoughts out of my head. It’s been DAYS and it’s all I can think about. I wonder if guys function like this too, or I’m just ovulating😭
