2 for me :-)
1. My beautiful wife... been together for allmost 10 years. She had a little more experience - but since I made her cum for the first time in her life - that never bothered me
2. We have been experimenting some - and got real close friends with a couple .... all had some nice times.... but distance (halfway across the country) and they having a baby did put an end to the sexual side... at least for now.
