What should I use with 37 y/o MILF? (I'm 24)

Yes, for a great many women, there is s strong social element to attraction and although her age suggests sexual/status, you do get exceptions and she could well be one.

So if you feel she responds well to social-based mixes, start with Ammo/IO as your primaries, don’t load up on the TUTH, at least until she’s relaxed and you get positive sexual indications building up. Then is the tome to add TUTH.
