Unplugme, you're on the right track, ok if you chickened out a little, but keep working on it, and find a way to talk openly about sex and sexual needs. Good healthy communication is very important to the future of your marriage IMHO. I seriously doubt you would be posting here if you just needed to get some ***** as someone inferred earlier. I don't think people stepping out is ever that simple. Sex is a very complicated thing, physically and emotionally, and unless someone is in your mind, they don't know what's really going on.

People with different sex drives find ways around it, if they're both open minded and want to help each other be satisfied. Even without a third person involved.

Best of luck.
