That is your biggest problem right there. Your question is like you asking, "how does this fruit taste like? I've never tried it before"
Some say sour
Some say sweet
Some regret tasting it.
...Actually, your case is more like, you haven't even seen the fruit. You don't even know what it means to be together with someone. It's a commitment to a partnership with an imperfect person. At any point of time, you both will experience shits or have to deal with each others' shits, so it's important to remember the good times together, and how she behaves in the bad times. It also means that you'll lose freedom to make certain decisions because you need to consider your partner/families.

Without any experience, there's no way you can tell what you truly want. With every encounter, you'll learn more of that. It doesn't need to progress into an official relationship. If you struggle to meet new people then consider dating apps but read more in the pinned thread to understand how to protect yourself and present yourself better for the type of person you want to attract.

Only then you can answer your own question, whether you want marriage or just stay single. Note: it's totally normal that you change as you be together with a person because you reconcile your preferences and values. Even if you regret today, you might not in 10 years, and that's fine too.

Easy, Ramjade already has a template answer for this
Short answer: don't flaunt, eat cheap, observe her

Lol, uncle silverhawk ady pointed out his self fulfilling prophecy where it's an endless vicious cycle of people using one another for fun and no strings attached. No one can talk "pure love" to this alpha male, but I'll see how you humour each other
