sexual positions!
all off of google! plus, since you say you two were not sexually expierenced before you got together, i would HIGHLY HIGHLY HIGHLY recommend
The Guide to Getting it On! by Paul Joannides. i considered myself pretty well-versed in sexuality and then i read this book- it is funny, well written, and very very informative about all things sexual. like, every teenager needs to be taught sex ed from this book
sex is fun! approach it as fun! and remember that sex isn't just about penatration- it's about using ALL your god-given talents to focus on each others' pleasure!
