Hello

My girlfriend really wanted to have a 3sum with another girl.

I told her I thought there should be rules (ie i wouldn't touch the girl). However, she refused to allow rules, saying she just wanted a normal 3sum.

At one point during the 3sum she didn't want to join in. Getting the other girl to climb on top of me. She continued to play with her and i a little below, but wasn't overly involved.

She later told me that she now thinks I cheated on her, and that she can never think the same of me.

What should I do?

She asked her friends about it and they all agree I'm an asshole. But I was only doing what I thought she wanted.

Any thoughts on this? I could really use impartial input.

Thanks;

S
