Well women have been doing this since the dawn of time, and it’s very doable.
Main thing is to make sure that you’re safe and not cheated of the money. The usual way to ensure that is to have some kind of agent as a go-between for you and the man. The agent usually helps put the two parties in contact with each other, sorts out the payment terms, and resolves any issues between them, including making sure you’re safe.
Having said that, it’s normal and natural for men to be attracted to young women, and value them very highly, and pay good money - much higher than any other female profession.
There’s two basic ways. One is a large number of men, and the other is one guy, usually at a lower rate.
What it means is that some women say, “If you want sex, it’s going to cost a lot of money, right now.” This is the origin of prostitution.
Other women say, “If you want sex, then you don’t have to pay a lot right now, and I’ll give it to you on a delayed-payment basis, but I want a joint share in your income and assets for life.” This is the origin of marriage.
Then between those two extremes, there’s every variation: gf, mistress, concubine, a woman with two or three part-time guys, “good girls” doing a bit of freelance for extra cash rarely, or occasionally, and so on.
As you can see, marriage is a sub-set of prostitution.
They both have in common that women expect to get, and men expect to give, valuable benefits to women in consideration of consenting to sex.
However the more men a woman has had sex with, the less everyone values her.
This means that your value at present is at the highest it’s going to be. It drops off steeply after 19. Tens of thousands of dollars is not uncommon for the privilege of bedding a woman of your age and stage.
Not only that, but the guys with that kind of money are usually better-mannered and better in bed than guys your own age with neither money nor knowledge of how to bring a woman pleasure and satisfaction in bed.
