I'm very good at meeting women, if I get the opportunity to meet/talk with them, and we have great first-time conversations.

We'll usually meet, I'll leave her alone for about a week or 2 (used to not wait that long at all), and the next time we talk I'm like "So what do I do now to get her interested?" I run out of hat tricks, so to speak (I don't use a game plan/list of things I do).

I guess, since I find myself constantly having to start/lead a conversation with a woman, I tend to get stalled in having extremely clever things to continuosly come up with. And I don't have problems making women laugh.

What suggestions would you have for a 21 year old guy trying to get women to like him off looks and personality alone? (Besides trying to trick her into wanting me with alcohol)

TL;DR: I feel like I have the skills to spark a girls interest, but am confused on how to keep that spark going, and keep her interested sexually.
