Anyone had any successful experience with it? I'd be interested to hear what % of firmness was achieved. My bf was only getting to about 75% (at best, often only 50%) on his own & it just wasn't stiff enough for good sex. I could barely feel it, although I haven't told him this so as to not further dent his ego. But he knew it wasn't great. So last night he had this ridiculous grin on his face & I just knew he'd popped a pill. But neither of us said anything & we pretended all was as normal, took our time etc. Anyway, from my point of view it made barely any difference. Maybe another 5% (at his peak) taking him to nearly 80% but still not enough for a thoroughly good stiffy. I can still barely feel it inside me & he has to pump away like mad to get any kind of friction. It was crap. Has anyone had experience of a rock solid erection on viagra? I have a friend who sung its' praises from the rooftops but they always took two at a time & I'm scared of the consequences of that kind of thing. I just want him to be able to get a proper firm cock.
