You and him can check out this site
www.askmen.com
it is a site designed for males but it covers alot of things in regards to sex and its pleasures. Just dont be offended with some of the male terms the authors use at times.

i hope you dont just rush into the intercourse hoping for an orgasm. there should be consdierable foreplay to ensure you are ready to be satisfied.
Anyway check out that site and see if ti can help you two!
