Yesterday I (21m), was at a party and were approached by this girl I kinda like. I could feel she was at least a little bit interested (touched my arm and leg/ leaned in quite close), but after around 10min of talking other people joined the convo and the situation was pretty much over.

This whole thing just showed me how bad I really am at game. Im a kissless virgin who rather spend my time at the gym instead of parties, so my experience is limited.

Where can I learn some respectful, basic game, in order to escalate? Not trying to become some creepy incel, just something (a gameplan/strategy of sorts).

Any help from you chaps would help ;)
