I'm not sure this will even be an issue as I think the majority of men see contraception purely as a women's issue.
About 10 years ago, I knew two women who were single in their 30's, both stable women in secure jobs, thinking about their biological clocks. They decided that, whilst they weren't going to actively try to get pregnant, they were going to stop taking precautions against it and see what happened.
They were completely honest with every man they slept with, "I am not using contraception, I am happy for you to do so if you want, but if I get pregnant I am keeping the baby'.
One wasn't in a relationship, had sex with different people, the other in a casual fwb situation with a man already in a relationship with someone else.
Not one man chose to use a condom.
One got pregnant, and now is a fab single mum, the other didn't and sadly won't have children now, as she's too old.
