How do you guys masturbate

I’m currently living in Lincoln tower and the shared bathrooms are fucking with me. I haven’t been able to masturbate since I’ve moved in and I’m going insane. I don’t have any privacy or alone time and each day I’m getting worse. I can’t even talk to females on my floor anymore because of how constantly horny I am. I need release. If anyone has any good tips or spots please help. I am really desperate.
