“Every single girlfriend I had, I asked her to get off contraceptives” is the tone of someone who is not interested in conversation and wants control. Bottom line.
This dude's girlfriends are free to tell him to fuck off (as one did) so there's no actual control.
There's a difference between "control" and "being on the same page about big deal stuff." I don't think my wife would marry me if I was a heavy drug user for example. That's not her controlling my life, it's her having a standard for herself. If we are not on the same page we just don't get married.
Presumably this dude doesn't want to date/marry someone who takes on heavy health risk when other options are available, especially when the nature of his can impact fertility and children. That's a very reasonable stance for him to take in his own life.
Likewise, my friend asking me to stop smoking because they care about my health is different than my boss saying to stop smoking or I'm fired.
