#1 tip: Don't have sex or long make-out sessions with any of them! This will ruin your reputation. If you have physical wants, you must pick one but it must be consenual. Promise nothing and make sure they realize this. If another fancies you, then they just have to wait until you break up OR you can have regular friendships with everybody and never be lonely...the sort of all-around good guy/girl. Sex ruins everything. If you cheat, you will always get caught. Sometimes they know but never tell you they know - that's even worse. My brother kept up friendships with a lot of people but visited a brothel for his personal pleasures. All his female friends thought he was celibate!!....al contrare!! !! Yeah...he was a gentleman alright.
