What age range of women would you say are the most receptive?
I'm in my late 30s. Throughout my 30s, the women who have been most receptive to me have been same age (but younger) to up to 4 years younger. I've found it difficult to get and to keep the attention of women more than 4 years younger. I was once able to get a date with a woman 10 years younger, but that was a "one date, no sex, no second date" type interaction. That was arranged via swipe app before I quit swipe apps.
If a man uses swipe apps, he's not likely to get a big age gap because women have such a huge advantage there. Women can maximize their advantages. For most men, swipe apps are a good way to date down on the SMV spectrum. The guys in the 8-9 range are even dating down, as they are often dating someone 2 points below them on SMV. It's quite common on the swipe apps to see a guy who is an 8.5 with a woman who is a 6. The 8.5 guy pumps the 6 woman for anywhere from one night to a few months, then dumps her to pursue a woman closer to 8.5. The 8.5 guy is more likely to find something sustainable with a woman in the 8-9 range through some method where the first interaction is in-person (social circle, random approaching, co-ed sports league, structured event, etc). If a man uses some method where the first interaction is in-person, he's also more likely to get a bigger age gap than 3-4 years.
Add to that women holding off to have kids into their 40’s (yeah they’re insane and think they can afford 60k of IVF with the right provider) around here many say they want children - again not my vibe and I’m no longer viable for them as a result.
If a woman reaches her 40th birthday childless, she's likely not going to have children. It's not worth doing the IVF. At that point, adoption could become an option, but that's also a difficult path. It's not easy to get 2 40 somethings to agree to an adoption.
