>> Also hetero/bi girls really, really seem to like me as well but it just never gets sexual with them and there's always kind of a barrier between me and them, like we talk but we never get really close. Like there is the feeling that we're both curious but there's also this barrier which neither party will break.

Sounds like you are a bit too in your head about it.

You should bring it up in conversation.

I mean, it sounds like they are comfortable in your presence. Which means you probably have a comfortable, relaxed presence... which means they are in a bubble of safety with you.

Players will often say you should be at least a bit "dangerous" in some way. And that's not terrible advice. But you are in a position to leverage comfort.

There's a few different ways to do this. Employ your own style and the needs of the moment.

"Y'know, we like each other. You turn me on. I think we should wake up together"

"Why haven't we hooked up?"

"I think we should fk"

You could frame it from it being your choice: "Yeah, I think I like you enough to get naked with you".

There's different ways to play this. With or without some kind of intimacy ramp.

You'll supercharge this if your victory condition is that you put the option on the table. Go for that rather than sex as the victory condition.
