Guys, how strong do you crush?

I never really thought guys crushed heavily. They always seem to have a few girls they are interested in, not one major one. I have some questions.

1, do you obsess? (You seem calm and cool whereas girls tend to obsess)

2, do you get strong crushes on girls where you cannot think about anything else?

3, if she is in a relationship would this impact how you feel? How would you feel about seeing her with her boyfriend? Pics on social media etc… would you avoid looking?
