Firstly, if you think women are attracted to you because of your looks then you don’t know women. It is, without doubt, a truism to say that you can laugh them into bed.
That's a bit harsh, particularly as it is not, as you suggest, a truism for the vast majority of women (and especially sub-40 yr olds) who won't go to bed with you if they find you unattractive, no matter how funny you are.
surely looks also play a part. And a big one at that.
I suppose money would be a good reason to keep them interested, if that's what they're after, but I doubt that's enough to get the apparently genuine connections some of you describe. Which is precisely why I'm asking about this.
Looks do play a part and is part of the mix but not always a big one, and personality/your approach is more important in establishing a connection with a SB.
In summary, success on SA is a cocktail made up of money, personality, looks and how you treat a girl, with the measures for each of these individual ingredients varying depending on the girl's priorities and persona.
