Age... It's Not Just A Number
I'm tired of hearing "I am mature for my age" because in my experience, that's just not so.
If they aren't busy trying to party on your dime, too busy partying somewhere else or hanging out with their friends and not able to make time for their "SD" then what the hell do they think they're doing?
Apparently there is a misconception out there that you can make little or no effort and get something for it. Or, as long as you put out a couple times a month, they don't have anything to do with you.
Any time I've seen an SD situation portrayed anywhere, it's quite the opposite. The girl is actually respects her SD, and is available for him. Prioritizes him sometimes over her own social life. Why? Because he's probably paying for a decent amount of it.
So once again, it comes down to this. Just have your shit together and stop lying on your profiles or saying whatever it is to get what you want. Just be honest and you'll have a much richer, more fulfilling and longer term relationship. You'd rather have one SD providing for you than 100 with all their weird diseases, fetishes or demands, wouldn't you?
