I'm a woman that is only romantically+physically attracted to women, but have been really sexually attracted to men in the recent past. Particularly with a neighbor that I've wanted to sleep with for a few weeks. Even though I haven't explicitly said I was gay the understanding is there just because of casual conversations. He flirts with me, and seems like he might find me attractive, but hasn't tried anything past that and is completely respectful. I just don't know how to approach him with the proposition to just have hot, unattached sex when I'm certain he doesn't think I'm attracted to men. Any advice?
