What can I do to stop having nervous bowel movements?

When I get excited about going to see the boy I love or nervous about hanging out alone with him, I have to poop. Everytime. My stomach gets really upset and it cramps and then I have to poop. In most cases it's diarrhea and I never feel like I'm okay by the time I have to leave. Is there something I can do about it to limit it or just stop it in general? I love knowing that I get to see him but I hate the baggage I get beforehand.


Why do sexual assaults happen?

I was wondering what the main reason is behind women getting sexually assaulted. Is it because of the way they dress, the way they act, or how easily tricked they are? Do girls say something provocative that entices the male to engage in sexual assault?
