The autistic forum members here have had extreme difficulty with the concepts of condoms and birth control.
Condoms are good in preventing pregnancy. When a man uses condoms with a woman who isn't on birth control, he still has a very good chance in preventing pregnancy.
Most younger women tend to use birth control. There's a good chance in any given interaction that the woman is a birth control user.
In a situation when a man uses a condom and a woman properly uses whatever birth control method she uses, the chances of pregnancy are very small.
In general, a man has a better chance of convincing a 22-32 year old birth control using woman to have sex vs. a 45+ woman.
I think part of the reason that you have convinced yourself that you like substantially older women is that you have acted passive in a lot of interactions. Younger women don't have time for passive men with the abundance that they receive. While few older women are into substantially younger men, the older women that might be into that might be more ok with passive behavior. Sometimes the older woman will be the initiator in an interaction with a younger man or be more inclined to escalate if she's sexually interested in a younger man.
Fixing the passivity issue is likely to help.
I went through a long stretch where I relied on condoms to get with many a young woman.
I have a file on my phone of all my smashpieces. After consulting my file, 15 of my 28 partners were below 40 (youngest was 21).
Of those 15, there were 3 who were already pregnant. And there was 1 where I demanded proof of birth control (she obliged).
That leaves 11 partners who were either 20 or 30 somethings where they:
1) weren't already pregnant
2) nor did I have any idea whether they were on birth control.
Then, starting at age 31, I ended up on an unlucky streak. I've had some condoms break, as well as a condom slip off. In the time since my first scare (a condom slipping off), I've only been with a woman below 45 twice.
Long story short, I threw caution to the wind (and started trusting condoms), only for condoms to eventually break my trust (no pun intended)
I find it interesting you say a man has a better chance of convincing a 22-32 year old to have sex than a 45+ woman. Supposedly, many a woman's sex drive skyrockets in her 40s (and on the other hand, a young woman...especially toward the younger end of the 22-32 age range, is notorious for having lower sex drives than men)
The 45 year old married woman I had the affair with at 23 said she had become uncontrollably horny to the point of putting her phone inside her cooch on vibrate.
If we're talking about, say, a 60 year old woman, I'd agree there's a high chance they'd be low sex drive. On the younger end of the 45+ demographic, however, not so much.
It's quite possible the passive thing is why I've had a decent amount of luck with older.
