Many many times. I very frequently go to night clubs, bars, etc wearing something very nice and sexy dresses. There I meet some nice guys and then go back to their house/hotel with them for sex and return the next morning. I do that especially a lot when my boyfriend is not in town. I love the feeling of meeting and flirting with a stranger, letting him feel me here and there and then finally letting them have their way with me in bed or elsewhere without even knowing their names.
