I respond to ads on W4M all the time with very few actual responses from real women but so far the three have been real. I am single and can host or as in one woman go to a hotel, she booked the room.
All of these meet ups have been nothing but wild sex, all told me they were married but I really did not ask or care about their status. Two of them were about as beautiful and fit as you can get and even though the third one was on the curvy side her sexual appetite was amazing. I have had multiple orgasms in the past but never had to tell a woman before that I did not think I was going to be able to have another one, I think she literally sucked me dry. The hotel woman has contacted me back for two more meet ups since our first encounter.
So while 99% of the ads are fake when you actually get a real one hold on to your hat because she will ride you hard.
