MILFS can be a lot of fun.
However, you have an uphill battle ahead of you.
I've dated quite a few, and they get peppered with messages from young dudes-even good looking ones, all the time. This is one area where good looks can actually work against you, if that's possible, because they will just think you're bored with your current conquests and looking for
"hit the cycle".
Basically look at the way society views this. I date some younger women, but that's considered relatively normal, as long as the age difference isn't too extreme. But even if it is, most people won't care.
Because it's easy for a woman to get boy toy, it's viewed completely differently. They are seen as craddle robbers, sluts, etc...
The other thing you have going against you is your very young age. If you were say, 30, and trying to date 40, that's a little different.. you very well could be an established adult by them. In your 20s, your going to be seen as young, not established, and immature. In fact, half the girls I have dated that our your age or slightly older, wont even date guys your age for that same reason.
Wish I had better news for you, my friend, but most of them will be very suspicious of your intentions. The girls I have typically talked to tell me the think the younger guys either want to brag about their conquest after the fact, or think the older girls can "teach" them something.
In any case, they are still women, and most of the same rules apply. You'll just have to play the percentages. It's definitely possible to do, so Happy MILF Hunting.
