Don't feel bad, it's an interesting point of view. Wasn't the smoothest seduction but it went great, it's what counts in the end. Now chat a bit and maybe set up a date if you feel he's interesting enough.
Good luck, also try to go to events with your friends especially if girls are attending. You want as many girl friends as possible, maybe you wont date them but you might date their friends.
This is probably a good chance to have a good story to tell. Go for it (casual only). Never ever date a girl that's going behind her boyfriend's back she will do that to you too.
I had the same question and your reply is very usefull. Another question is: I have no idea about brands, or male fashion in general, should I go shopping with a bro or should I ask a girl (a girl I have no intention to fuck)
