I agree with most of what has been said above. We've had a few experiences with single women. For us, in each case it started with a legitimate attraction and friendship. Our first was actually with a vanilla friend who knew we were sexual and she simply asked if we would be open to it. It was wonderful. So, my advice pertinent to this discussion is to be politely open about your sexuality and opportunities will arise
The other times have been with women we met through an adult dating site. Each time, it was after a couple weeks of chatting back and forth, getting to know each other, and seeing there was mutual attraction, affection and a safe feeling. SO, here, my advice would be not to rush things. Single women have tons and tons of choices... its really helps if you legitimately like each other and can connect non sexually as well. At least that is what we've found
