Like enema quantity, its not a contest. The feelings are wonderful. Lets not be in such a rush to get them over with.
I've got two different estim systems, one at home that is driven off a computer audio wave form generator, and one "vacation" system that is just a Tens 7000 kit that goes along when I travel to my winter place. Either one is capable of delivering an HFO. The orgasm from either is stunning, but the speed at which its delivered is about the last thing I am thinking about.
The home system allows an unlimited configuration of frequencies, wave forms, and patterns. I can spend a couple hours creating new and better feeling audio files. Sure, most often, in the end, I find something I especially like and just push the levels till orgasm occurs. While it feels fantastic to cum from the estim, the time spent playing with the audio files and the feelings they create is easily half the fun.
The vacation system, the 7000, is so much simpler, but its completely portable! With an anal insertable, and a glans ring, I can wire up and head out to the grocery store or wherever with the 7000 clipped to my belt, or in a pocket. I usually add a condom, or some other plastic protection just in case things down there get extra juicy This lends a whole new meaning to getting a twinge below the belt when you meet that hard nipple gal in the frozen food aisle 😃 If its a lazy morning, and MsLog has a headache, (thankfully that almost never happens), I can spend half a day enjoying the erotic sensations of estim while dressed and working around the house. Point being, that getting there is half the fun and I don't want to get it over too soon.
Relax. Enjoy! HFO will happen when you don't demand it to operate on your rigid schedule.
