I'm 38, wife is 29.
I've always had an extremely high sex drive. I'm down for sex pretty much any time but noticed that occassionally I wouldn't be fully hard. Not all the time, but sometimes I'd get only about 85% hard. Still possible for sex, but obviously not ideal. Usually related to being a little tired, but sometimes stress.
This bothered me, so I went to Amazon and bought a natural vitality pill just for kicks. I didn't tell my wife because honestly I'm embarrassed that I purchased them.
I popped one of these suckers before having sex the other day (I knew we were going to later on). Had a slight blood rush to the head for 10min or so but that's it.
Holy shit.
My dick was like 25yrs old again. Throbbing hard and aching to get to work. My wife was really turned on by how turned on I was... she rode up and down my cock that day and I kept 100% hard the entire time. She bounced around more than usual and I loved watching my cock go in and out of her.
I'd occasionally say things like, "you see how hard you make me?" and she fucking loved it... got even wetter sliding up and down my dick. I grabbed her sides and moved her up and down my shaft, she put her arms by her sides and just gave me that submissive look as I used her pussy to make me cum. It was hot.as.fuck.
I think that stuff stays in your bloodstream for 24hrs because maybe only a couple hours later, I was fully hard, ready to go again. She wasn't in the mood, but the look on her face seeing me so turned on again for her even after we just hooked up... omg priceless.
Anyway, I don't take this pill every time we have sex, but now and again I do and it's always good. I never thought I had a problem really, but I suspect as I've aged my testastorone is going down and that has impacted me in certain moments.
I'm not here to promote any one pill, but just search for "natural male vitality" on Amazon or in your favorite drug store and you'll have plenty of options.
**EDIT:**
I keep getting DMs about the one I used. It's called Pure Superfood Power. They don't sell on amazon anymore, just their website.
