Back in the late 70's, when I was newly married and still in my teens I wanted to buy my wife a vibrator.
Found the only adult bookstore in my area and went inside. Damn, it stank of old semen and was mostly dark and full of older men shuffling around looking at each other with funny looks.
Not very appealing and I'm sure glad I did not take my wife.
After looking around for a while I found a plain white dildo with a screw base where you could take the batteries out and also adjust the speed.
For such a simple item, it was still very expensive. Must have paid more than $25 or so for it. Then had to go buy a bunch of C batteries.
When I got home and showed my wife what I had bought for her, she was not too impressed. It was made of hard plastic. It was loud as hell once she turned it on and it really only had fast and faster.
We tried it out together, but it really wasn't that much fun.
However, about a year later I got shipped overseas to S. Korea since I was in the U.S.A.F.
While there she sent me a tape recording of her playing with that vibrator. What was so interesting about it to me, was the sound of that vibrator's loud hum going in and out of her vagina as she pleasured herself for me. Talking to me through her experience on the tape, it was almost hilarious as that hum would go up and down in tone as it went in and out of her....all the while she's telling me how good it feels and how she's dreaming of it being me.
Then she got to a point where she could not keep talking, but that damn vibrator just kept on it's hypnotic pulsing sounds. In and out until she came so hard she dropped it on the floor still buzzing!
So glad I don't have to go to some nasty old adult bookstore to get a toy these days.
