Hi Matt, the best way in my opinion and what is usually the known way of showing interest in someone, is firstly dont rush in too quick give them a couple of mins to settle down, then when your ready, a gentle caress on either their arm or leg is well known sign that your interested. if they are interested in you, they will usually allow you continue, thus maybe moving onto oral or mybe more. However you also gotta prepared for people to reject you….this will either be expressed as a polite no thanks, or they will kindly push your hand away. if that happens, just accept it and move on. Of course this also applies to you if someone approaches you aswell. Just remember NO means NO so dont try and pursue the same person any further. 🙂
