No, I wouldn't. For these following reasons:
1. Girls who don't want to have sex until marriage are usually very conservative or very religious or both. That's not the type of girl I want to date. I am very liberal and non-religious myself and I can't really deal with stuck-up people well (no offense but I don't like it when young people talk like 80-year olds).
2. Girls who don't want to have sex until marriage are usually also conservative about sex. This means that the girl won't be willing to experiment and try out new stuff and that sounds like a recipe for failure. Sure, in the first 3 years of your marriage, you won't care but at one point, you wanna try something new and I would hate it if my wife just always said "no, that sounds really weird!"
3. In German we have an idiom that goes "to buy a cat in a bag". It means to get into something without even knowing whether you're gonna like it (because the cat's in the bag when you buy it, you can't see if it's healthy or not). I don't want to buy any cats in bags. Sex is an important part of a relationship and I'm not willing to take the risk of getting into something where I later find out "wow, this girl really sucks at sex". I'm not saying I would necessarily break up with a girl just because she sucks at sex but as her long-term boyfriend I believe I have the right to KNOW whether she's good or bad at it. If I get married, it is my utmost interest to make the marriage last. However, this is only possible if I can make an informed decision. And I can only make an informed decision if I know as much about my girl as possible. Naturally, that includes sex.
4. Lastly, I personally don't get why anyone would wait until marriage with sex. That's like saying "I'm not gonna drink any alcohol until I get married". It just seems very silly to me. I think it has to do with the fact that most virgins think of sex as something reeeeeally big and special because they've never actually had it. But the truth is: it's not. I love sex but it's really not that special once you've had it for a while. Conservative girls who want to wait until marriage frequently make this distinction between casual sex vs. sex when married, assuming that sex will for some reason be much more intimate and romantic if it's with a person you love a lot. But as somebody who's been in a long-term relationship I can tell you that even if you have sex with somebody you love dearly, 95% of sex is pretty casual (quick fucks before work etc.).4
