I hate to generalize this, but I'm going to do something I rarely do...and that is to generalize here. Most women, when an affair starts aren't looking for the physical aspect. There are other needs, often emotional, that aren't being met that somehow the OM does meet. Often affairs that women get involved in don't become physical for quite some time.
I just wanted to point out that she may not necessarily be thinking sexually...when it comes to the OM. She could be, but it's not necessarily the case.
