Also, single men are a dime a dozen on those sites so if you have any hope of getting together with anyone you need to make sure that you make a decent profile and only contact people who say that they are specifically interested in single men I'm assuming that the OP is male but if not she should have no problem finding a couple to watch because solo women are rare and highly sought after on those sites. I live in an apartment home and it turns me on to hear my upstairs and next door neighbors having sex. If we like them and they us, we could do it again, perhaps the next afternoon or evening. She was quite vocal and had a very high-pitched voice. When we go on vacations we would leave the hotel curtains open and do it right near the window for others to see. DH and I have done this too.. If you find a couple that looks good to you then shoot them an email asking if they'd be down with you watching or taking pictures or whatever.
