I feel at the age of 37 the window of opportunity to marry a woman who is relationship material has almost closed. The good ones are taken and the ones that are left are single mothers and women who have a lot of problems/baggage (not saying that I don't have any problems, I am far from perfect). My friends who have married are with women who they met in their early to mid 20s and are not only just a couple romantically but also each other's best friends. They didn't sleep around much before meeting each other. They dated around 10 years before getting married, they didn't rush anything. Hopefully everything works out for them but as other posters here have mentioned, as a guy getting married nowadays can be a raw deal.
Back in my early to mid 20s there was the whole PUA (pickup artistry) forums for tips on meeting and sleeping with women, then there was The Red Pill forums discussing about female psychology and how the dating world really operates, then there was the MRA (men's right activists) forums on guys who got screwed over in divorce courts and are not able to see their children on no fault of their own, then with that came the MGTOW (men going their own way) forums for guys (either by choice or not) washing the idea of getting married and are living as childless bachelors. All of these spaces had a lot of Gen X and even some Baby Boomers telling younger guys to NOT get married. Obviously there was genuine misogyny in a lot of these places and are a minefield to navigate through but there were a fair number of stories of guys getting cheated on, swindled in divorce courts, finding out the child/children they were raising were NOT biologically theirs but had to pay child support anyways because they signed their birth certificates, and being victims of verbal and physical abuse and were just old to suck it up and cry about it later. A guy doesn't even have to be married to deal with this garbage, common law marriages where a woman lives with you for a certain amount of months makes you vulnerable to all of this shit.
Reading these stories has made me (and many other Millennials) realize that I should just avoid marriage because as soon as one becomes a husband they basically become a 2nd (or even a 3rd) class citizen. Most of my friends as of now are single (either by choice or involuntarily) and I don't see that changing at all. I didn't age very well and whatever looks that I had are now gone so it's pretty much over for me. Even when I was younger I was hopeless with women and outside of this I've only hooked up with two women in my life, I have never had a girlfriend.
With how male-female relationships are heading it's not going to get any better, it will be more of a winner takes all with fewer people getting married. I feel that more than half of men my generation are not married and won't be having kids, not really good for society to be honest. I also don't want to bring any children into this fucked up dating world where only the top 20% of men get all the women while the rest of the guys get nothing and more women are ending up as single mothers or spinsters who regret not having any children as their child bearing years are over and hate men. The other thing with a lot of these women is that when they were young they got chewed up and spat out by the top 20% of guys while treating the other 80% of men with distain and contempt. No self respecting guy wants to deal with that kind of disrespect and have someone with an irresponsible approach at life in their lives. Yeah being lonely can suck but it's better to be alone than to be with bad company.
I really do feel bad for the younger generation of men having to navigate all of this shit in the dating world. Safe to say more men will just not date altogether (either by choice or involuntarily) and either do this hobby and/or become absolute gooners and just consume pornographic material (or even transition into women because we're seeing a lot more of that now).
Also, being a childless bachelor means that I don't need much to survive and can live off of a job that I can tolerate but not really care about, and if said job starts to treat me like crap I can just leave because I don't have a mortgage and/or a family to feed. I have become more frugal as I get older so I don't need much.
Sorry for the rant but yeah I just see myself staying single and doing this a few times a year. A part of me would like to start a family but there have been many men who were way smarter and more hard working than me getting completely screwed over not just in marriage but in relationships in general.
