Men can still be physiologically satisfied by said rubber sheath, because all they're really physiologically driven to is to orgasm. Women are physiologically driven to want babies, which nothing can satisfy except having or adopting one. I suppose they could adopt a man and they'd essentially have one too.
First off, if you can be satisfied by a condom alone, I feel sorry for your dates. Secondly, if you don't have the vagina or the scientific studies to back that statement up, I call misogynistic asshole.
The question was whether or not women had more choice in the matter of parenthood, and the fact that they do, simply by virtue of their reproductive system being the easiest to manipulate, cannot be disputed.
