Alright, here is what you're going to do. You are going to live your life like a 'normal' human being. You are going to meet girls, hang out with them, and go on dates.
This is the most important part. You are NOT going to be creepy about it. There's basically two ways your new relationships are going to go. You wait until she is comfortable with you being close to her, hug her, kiss her, and having your hands on her in general– and THEN you play-fight/tickle/etc, and THEN only wait until you know your relationship is at a sexual point, and then let her know, honestly, what a few of your lighter kinks are. Girls are more open to tickling/light bondage/footrubs, etc, because there is no percieved danger, so no creepiness from your side.
The second way it goes is this: you meet a girl, you tell her early on how horny you get when you tickle her, put her through the light mental stress that is denial/forced orgasms, and generally speak as though you've been looking FOR this rather than her company, and it comes off creepy.
There might even be scenarios where you date a girl a few times and you massage her feet and tickle her a little bit. This is normal. The important part is to introduce it as playful tickling and flirting RATHER than "I want to do this for hours while you're tied down." There's a pretty big distinction, and if you hope to actually get someone into it, you can't drop them the endgame. If you were introducing someone to anal, you wouldn't find the biggest dildo and ram it up there, so don't do the same thing with tickling.
tl;dr don't force it and don't be creepy.
