I'm about fourteen years younger than this particular individual. We're good friends and have been on two recent 'outings', just the two of us. Both of them went well and we talked a little about budding interest in each other. I want to know how to seal the deal - how to convince him that I'm the tail he wants to chase, to coin a phrase. Thoughts?

edit: (clarification) he's been on a (to my knowledge, just the one) date with someone else. I don't know anything about her, except 'they kind of hit it off' but we're still going 'out' again tomorrow, that's really my curiosity, what with the other woman and all.
