Many of them have sexually explicit photos posted on their profile pages and they don't want these pics being spread.
So if you recognize someone on an explicit picture than please DO NOT distribute it on social media and respect everyone's privacy.
At My Sex you can view photos and chat to make sure you are both on the same page. Remember that you are here for no strings attached sex, so you might want to use the site to meet and fuck as many people as possible (the more, the merrier! You can sleep with a partner without any promises to each other, so if you get tired of your shag buddy now, then move on to the next one. Life shouldn't be taken too seriously - sometimes it's about having fun and experimenting. Experience of conducting sex dates comes over time. You need to be engaging on the date but not over-keen, flirty but not sleazy, and you need to feel relaxed.
That way you can avoid uncomfortable conversations about what you both want when you're sat across from each other! Many women comment that a man who looks comfortable in himself is extremely sexy in their eyes.
No, of course not - if there was mutual attraction, they simply had sex!
