This topic comes up a lot, and I'll give my usual answer. "10-15 year age gap (*above legal age, of course)."
In my experience, mid-30s was my peak. I lead a stable life free of serious drama, established in a career, got money in the bank, basically 'got my shit' together. Along with the added perk of still being spry enough to be seen as still youthful and all the benefits as such. I could still keep up with a 19 year old provider; that is if they actually exist. Another thing I always say here is that "19yr providers are a sort of a unicorn in this trade." Even if you can find one who is professional, non-judgemental, not trafficked, and truthful about her age, you're still mingling with immaturity and/or inexperience.... which, again, is fine if you're an immature 30-35 year old yourself to accommodate each other's energy....a 15 year gap for success, imo.
Once I turned 40, it was like a switch flipped on. Energy lowers, and greying of the temples appear. Literally happened overnight for me. One time I went with a 20 year old girl and the chemistry wasn't quite there. Perhaps my older grey visage was turning her off, when the reality of her occupation dawns on her that 'the job might not be all fun high school type parties.' It wasn't a one-time situation either, another 20 year old I saw was a bit cold to me too. She was nice and accommodating, but I can tell she wasn't that much into older guys; we went through with it, because ...well, I was paying her, i guess.. So I started seeking providers a bit older, like mid-20s. And had a great time once again. My only assumption is at 25, the girl knows what the score is; know how the game is played better, realize who their demographic are, and for that they become more professional and accessible to a wider and older age range of clientele. ...still at 15 year gap for success, again.
As I'm getting older, late-40s, sort of getting the same vibe with mid-20'ers than I did with the last "19 year old" I was with when I was in my 30s. Just not a lot of connection, sure they'll go through with the session. Not really having a cold attitude, but usually feels like some of the chemistry is missing. So again, I bumped my desired age range to late-20s to early 30s, and again same results of getting that chemistry back; except with 'a twist' that I haven't quite established as red flag yet. I suppose time would tell, if I continue seeing them. But I've been with a few of 30yr old providers, and sessions with them have been great. Too great, as I saw one of them for a second time just recently. And two of these ladies keep texting me back, speaking to me casually like we're friends going on to be BF/GF, even one just asking me out for coffee (her treat), while sending me vag pics after shaving herself down there... I mean, I'm not offended, and do feel a bit flattered that I'm getting the attention. But I never had that from any other provider before, or should I say "any YOUNGER provider" before. So I'm a bit weirded out, since I'm obviously a man who's past being 'spry and young'. But in the case with "Coffee-girl", the way she texted me, I kind of had to remind her that I valued my discretion for obvious reasons, and gave her the whole "you know what this was" speech, and she would and she would nonchalantly say "she doesn't mind, she just wants to keep seeing me" while describing in very vivid details what she has planned for me when I see her next time; "no clock, all sub, not a drop will touch the floor" kind of talk... Either she liked me enough to want me as a regular client, maybe into a Sugar-Daddy arrangement, or judging by how strong she was coming at me, she might actually want be a part of my real life, in a 'homewrecking for a co-dependant relationship" kind of way... Again, never had this happen to me before, so the best word I would use is "clingy". I'd like to see her again, to see if she's really into what she was saying, but it's probably safer to ghost her. idk.
Anyways, in my experience, "15 year gap" between you and her.....not sure how being 60 is like with a 19 year old to see the '15 year rule' be tested. But I can't imagine telling her about my memories of being at a Nirvana concert, because she was wearing a Nirvana shirt and can't tell me the name of 5 of their songs.
