Thank you for your question.
The most sensitive part of the vagina is 2 inches at the entrance so as long as your erect penis is 2 inches or longer you won't have a problem. There are no medicines to increase size. Regarding having good sex maybe you could read a book called ' new male sexuality' by Bernie Zilbergeld. This will give you information on how to have good sex, not just intercourse.
best wishes
