Depends on what you want, really. Would you do something for someone else before you did the same thing for yourself? That kinda thing.
If I have any advice that I follow and have used once myself, given to me by my guardians in school and home, and from the huge, very sexual online culture that I've been a part of since I was 13, I'd say to at least wait for someone that you know you would marry if they asked you right then, or if the only reason you'd say no is to wait the socially constructed and fluctuating amount of time before you're allowed to say yes. If you're having doubts about that person, perhaps either wait until those doubts are cleared, or follow those doubts and search for another fish in the sea.
Oh, and this giant black part is what I was originally going to comment but it's a lot less important in terms of how good the advice is in my own opinion. You could give it a read, but it's really only backed by what I learned in the very sexual online culture which isn't really a study or anything.

I'm a guy (18) so I'm certainly a biased source, but some guys really appreciate it when someone waits till marriage. And then, there's some guys who really enjoy having a sexually experienced person. Heck there are some guys that enjoy their women to sleep with other men, but I can assure that that's a minority. Who do you want to attract? What kind of personalities would be interested in the certain choices you make? I'm surely not experienced in the bedroom, but I'm in a very sexual online culture and laid my ears out for those willing to speak publicly, which is the severe majority. I'll lay down my perspective, if you're interested in that reading.
There are a few kinds of people that you'd attract by staying a virgin till marriage.
• There's the nice guy, who's all proper and uppity
• There's the traditional guy, who thinks sex is to be only between those who are married
• There's the incel, that refers to sexually liberal women as femoids and feel like they're entitled to their mate
• There's the NiceGuyTM which, while different from the incel in the way that they don't subscribe to such a culture, still has a kind of entitlement feeling
• And then there's the normal person who doesn't subscribe to any stereotypes because a stereotype is a vast generalization that doesn't accompass all or sometimes even most people in an idea.
There are a few kinds of people that you'd attract by losing said virginity.
• There's a type that prefer sexual experience in general, as I mentioned
• There's a type that cares more about personality than any kind of sexual history
• There's the incel, that just wants to bang
• There's the stud, that just wants to bang first and date second (whom I've had the pleasure to meet, many many times.)
• And then there's the normal person who doesn't subscribe to any stereotypes because a stereotype is a vast generalization that doesn't accompass all or sometimes even most people in an idea.
Though, imo, this should all be an afterthought to selecting a lifelong partner. If someone truly cares enough to turn you down over someone else getting first, or if someone truly cares enough to turn you down for someone not teaching you in the sack, perhaps that's some insight to their darker personality that they wouldn't show until 3 years into a marriage.
