Did this before. Not for the jealous type. Nervous at first, then eventually relax when you both feel what your comfortable with. I'm straight. She was bi-curious and tried it once. Not for her at that time. However, she is willing to try it again. Me being the shy one, I just pretty much watch now. It suits her fine, she loves to be watched. You'll have a great time. Last time was a MMF for her, and I overheard her say, once she orgasms, she will try anything. Thanks.....Joe and Mary
