Been using Viagra regularly every punt for some 6 years now, original Pfizer and generic here in oz.
Overseas in SE Asia fucked heavily in Zeagra which I still say works the best.

In Oz I take 100mg. I’ll split I. In half and take the first half about 1hr before I punt. Then as I’m driving to the punt I’ll pop the other half. Being with the right WL of course helps but I’m rock hard most sessions start to finish fucking.

Best advice I can give anyone is DO NOT take any stimulants with V. Don’t drink coffee or take Horny Goat Weed cos they clash and you’ll wake up with a fucking migraine.

Alcohol doesn’t seem to have much effect, I’m usually in 4-6 beers before I fuck and no issues.

Some side effects of V and its generics are the red flushed face but so what. It looks like a sex flush. I often take selfies with the fuckhouse front door and signage and my face is all pink and flushed after a hardcore 1 hr fuck on 100 mg V. Hehe

As for Zeagra, motherfuckers that’s is a God sent. My cock stays rock hard and vein popping the whole night in Asia fucking PYT’s and I don’t cum. Side effects are runny nose and flushed face but no headache.
