At sixteen. Yeah, good times.
Also, abortion, adoption, parenting...yes, those are all just super-duper awesome and are totally good alternatives to asking a dude to wrap it up if you're not sure he's being honest about whether he's had a shot/snip. Retroactive actions are always so much better than preventing the problem to begin with. And access to the morning-after pill is not exactly reliable. I was once in a situation in my 20s when it was a holiday and only a couple of pharmacies in town were open, and the one I went to had a pharmacist who exercised his right to "conscience" to refuse to sell me Plan B. I had to drive 45 minutes to get it--thankfully I owned a car or I might have been SOL.
Seriously, you want to avoid getting a woman pregnant, cool, get the shot. Do you trust every woman to be telling the truth when she says she's on the pill? I would be the answer is no given your rant about women's list of choices (the statement that women force men to do things around parenting is telling as to your ideas about women's trustworthiness around reproductive choices). If you don't want some woman to force you to pay for child support, then get the shot, but if she wants you to wrap it up too, then grow the fuck up and wear a condom. You don't trust her, that's obvious from your statements, so why do you expect women to just trust you?
I'm in the fortunate position to have a partner that I can trust, and we make reproductive choices together, but people don't always have sex with monogamous partners they trust on that level, and in those circumstances, believing someone when they say "I'm on the pill/have had the shot/am sterile/don't have any STIs" is just plain stupid regardless of gender.
So nope, I don't trust that all men will be honest about this stuff. I don't trust that all women will be either. If you do, then you're pretty naive about human nature.
