it's gotten to the point where I feel like most men will not give a woman wife status if they're getting the milk for free
I think this is a very outdated way of looking at things.
Sex should not be something you do for a man because he is willing to commit to you. It should be something you both want to do because you're attracted to each other, regardless of your marital status.
Many couples find that the amount of sex they have drops quite drastically during pregnancy and the first few years after having children. If that happens, it's important to be able to remember a time when you were having lots of great sex in the hopes of getting back there once your children are through the baby years and you're less tired. If you haven't had sex before your marriage and then you get pregnant quite quickly, the danger is that you won't have any real experience of having a healthy sex life together to fall back on, and you might just think you're not sexually compatible.
In my opinion the first couple of years of a relationship are when you should be really enjoying getting to know each other sexually. A year of abstinence with the aim of getting a ring on your finger and a positive pregnancy test as soon as possible doesn't sound very conducive to long term happiness.
To be quite honest with you, I think any man who is more likely to want to marry you if you don't have sex before marriage is probably going to be a bit odd, and maybe not the best choice for a life partner. (Assuming he's not waiting for marriage himself for religious reasons.) It is unhealthy to place too much moral value on someone not having sex.
Ironically, I actually think it makes sex more of a transactional thing, not less.
The majority of men, including the ones who, like you, want to get married and have children, want a life partner who wants to have lots of great sex with them.
If you treat sex as something you do to get something else you want (such as a wedding ring, or a baby), the logical conclusion a lot of men are going to come to is that you don't enjoy sex in its own right and will stop doing it once you've got everything you want out of it. And most men who want to get married and have kids don't want to be getting divorced after ten years because they haven't had sex for the last five.
If I were a man, I would see abstaining from sex before marriage (when you have had sexual partners before) and wanting to get married and have children on a particularly tight timescale, as big red flags.
It would tell me that you don't particularly want to have sex with me, and that you're more interested in being married and having children in general, rather than specifically being married to and having children with me.
