I'm not sure why I mentioned getting turned on by another woman, but the point was that it felt good to be "noticed".
After giving this some thought, the answer is simple. Most of the women that I actually notice may be attracted to me don't look that much different from my mom to me. That's why I mentioned it. This woman is actually attractive for a change.
