Hi, I'm a virgin man of 25 years old. During sexual intercourse for the first time, is it necessary to use pills like viagra or levitra so that the erection of the penis could be maintained for a longer time? As we all know, first time having sex might not be a good experience because men tend to feel nervous and this nervousness might cause the penis to remain flaccid. The partner wouldn't get satisfaction and this could lead create trouble in a relationship. Please let me know whether or not I should use pills while having sex for the first time. Thank you.
