Viagra is always with me. Since I have two girlfriends, who always want my attention, I have to use these tablets for the third or fourth time. In general, after two natural acts, while the girls are resting, to continue I take a pill and drinking half a glass of water. The instruction says that the drug is strictly forbidden to take with alcohol and sometimes I break this rule, but I’m still alive. We’ll see how much longer I’ll hold out) Viagra dilates the blood vessels in the whole body and then it flows the blood to the penis, as a result is an excellent erection. The action of the tablet comes in half an hour. The disadvantages can only be attributed to the fact that the skin rubs off because of many hours of sex. Once after 2 days in bed, there were headaches, but maybe everyone should have some limits in their desires.

To begin with, I never felt the need for this drug. I’m 26, a healthy man, with an erection and normal duration of sexual intercourse, always and everything was in order …
But I wanted to try for a long time. True, that my mind though objected, but not so much.
Curiosity took the same up – and now I’m standing in the pharmacy and ask to sell me Viagra. You should have seen the eyes of a girl – a saleswoman (my peer) at that moment … “Poor thing … Such a young woman” – was clearly read on her face. With some inner pity, she handed me a box with one single tablet and the price … !!!
But there is nothing to do – I take it and jump out of the pharmacy.
At home one more trouble awaited – my wife could not understand why I needed it. Type – “I’m not exciting you already?”. Despite all my arguments that this is a purely scientific experiment, I was offended. Since I tried not to try without it, I had to postpone it for another two days until the storm stopped.
And then came the day of the experiment. After work, I did not really have dinner, the drug took almost on an empty stomach. After an hour of waiting (all according to instructions) went to your beloved …
Well, I can not tell you that I felt some improvement in my erection. Apparently the tablet is designed for those who have a real problem … Or whom the partner does not excite so much 😉
As for the duration of the act, no changes were identified either.
What really intensified is a desire. Just like some starving male from the wild jungle ….
Of the side effects during an hour of waiting I can distinguish reddening face and slight noise in the ears.
Try it or not – it’s up to you.
Thank you. I hope that was useful for you.
