I tried small dose (10mg Cialis) to see the effect and i couldn't really tell the difference much from my normal routine of supplements for the most part. That being said my 'dance partner' maybe did see the difference since she couldn't take me completely for the first time ever (maybe it got me an extra cm of length through hardness) lol still TBD. Will try again this weekend lol
I had the same effect the first time I tried V.
It was only 25 mg but then again it was a non scored 100 mg pill cut in half and the in half again with a pill cuter.
Anyway it was someone I'd been seeing and when she saw it she said "why does he look bigger", it was actually distracting her from the normal foreplay and finally she just blurted out , "can I just ride get on top and ride him"? But she had already made up her mind because she was going for the lube and condom as she was saying it.
I think the reality is that with the extra help you get more blood staying in the penis thus a bigger thicker erection. I'm sure
@genius can verify or otherwise clear this up.
