Its good that you didn't prolong the kino, but its bad that you didn't keep on going.
You got discouraged because she didn't return the kino, which is the wrong mentality to have. The only time you need to act distant is when she actually gets uncomfortable. Not because she simply didn't return the kino. As long as shes not tensing up or moving back, feel free to keep escalating your touching.
You're right about starting and stopping and not prolonging it, but you just needed to keep going. Keep starting and stopping, but keep making bigger moves. Don't be discouraged just because she wasn't touching you back. If she took time out of her day to go on a date with you, she pretty much likes you, so don't worry about it.
And don't worry about seeming desperate. The only way you would look desperate is if she got uncomfortable or she made it obvious that she wanted you to stop and you didn't stop.
This is also why qualification is important. (I feel like I have to harp on qualification every single time I post). If you don't express that you like her and the REASONS why you like her (other than her looks) then she might get uncomfortable with your kino because she might just think you wanna get laid just for the sake of getting laid, not because you actually genuinely like her. When you qualify properly, kino often times becomes SUPER easy.
Thanks for both replies.
Re this one. Though, as it was only a first date, I felt my approach was enough to show her I'm sexually attracted to her and that I'm confident enough (well, I hope I am!) to do something about it. It felt that if I just kept going and going and doing bigger moves that maybe I'd appear like I'm on heat lol or that I'm only interested in one thing. Don't get me wrong, I pretty much was only interested in one thing (plus using the date for the practice), but I don't know if it's best that she knows that lol!
By the way, are you sure about using bigger moves? Even if my kino is still getting a neutral reaction from her? And by bigger I presume you mean more prolonged etc?
