People often feel so uncomfortable about the idea of buying pills for sexual potency (https://staminafit.eu), but that's nothing that we should be worry about.
Sexual education in certain countries is so poor that we don't like the idea of being related with those topics, when that's certainly something wrong that we sould avoid. Men's confidence should be something over that and don't be ridiculed by someone else.
