It depends on your sex drive and wallet size, and to an extent if you are okay with a sexual relationship with one person. If you have a high sex drive and want sex often, the hobby will cost you a lot. If you have the funds, than it will not matter. If you do not have the funds, you may be left disappointed.
But to find a partner where it's just about the sex, well that's also dependent on if you are okay with one partner. Or, do you want multiple partners. Obviously, the hobby makes that easy.
That said, be honest about what you want. Don't go looking for a girlfriend or future wife. Look for a friends with benefits. Make it clear that you do not want the courting. You want a friendship where you get to fuck. Then, look for what you would look for in a friend, the difference being you're dealing with women not men. There are women who like what you like, such as sports, music, tech, history, politics, etc... Also, at your age, there are plenty of women who just don't want a relationship either. They may be career women who also want someone to fuck and not waste much more time with them. You will only find your match if you are honest upfront.
But maybe it runs deeper than just this. Maybe you don't really want to talk to them even as a friend. How are you out in the world interacting with women? Do you have a job with female coworkers? Surely, you deal with plenty of women wherever you go, be it shoping, a sporting event, or anything else. Do you find talking to women outside of dating to be something you are disinterested in? If you don't like talking to women in any situation, then the hobby route is it. But if you have no issue with it, than you can try the honest route. Use the hobby for now. But if you get a bite, than maybe you can save money.
