Been a kissless hugless virgin for a long time, finally got a girl who clearly likes me, we've kissed a few times, she's clearly into me and wants a relationship. Problem is i dont think i have that much desire for it.
I always thought if a girl liked me i'd be super happy, now that its happened i dont care too much. I dont know if its her specifically or if im just not built for relationships because of being alone for so long. Thoughts?

Theres a girl that wants to go on a date with me, and a girl who im interested in but im friends with.

Plan is to go out with the girl thats interested in me, just to see what happens. Then ask the girl im friends with out.

Advice? Also how do i make it clear that the date with my friend isnt as friends but that i want more than that? Without being a nerd that says it outright
