M, Mid 50's.
I hit puberty in the mid 70's and the only men's mags we ever saw were Playboy and Penthouse. At that time Playboy just showed boobs and bush, but Penthouse would let you catch a peak at the lips. But if you ever got to see a Hustler, it was like WOW because they showed everything. Most of my masturbating was done to bush and boobs, so I guess that is what imprinted on me as time to get hard. So when I see the wife's bush, I get hard. But it can't be flowing down the leg bush, it has to be kept inside the panties with maybe one or two hairs peaking out. And that is a thrill young guys today don't get. Being at the swimming pool and catching a stray hair outside a suit. We would have to roll over to hide our hard-ons.
I also like bush because it is what girls had when I was in college in the early 80's and the way the bush kept the scent of her was intoxicating. I finally talked a GF into shaving in the mid 80's and found I didn't really like it. Sure you could see her whole vagina, but it just wasn't right. And she complained my hair irritated her when I was grinding.
As for hygiene, I don't mind a bit of sweat, but I do have one rule. If you want me to go down there with my face, you will have showered since you pooped. Bad experience with that and I never want to repeat it. In regard to the size of the lips, I grew up before women were so liberated, so if you were getting some, you were happy no matter what it looked like. I could not fathom the idea of telling a girl I wasn't going to sleep with her because her hoohah was ugly.
