So far my wife has had more partners or repeat partners than I have.
Do I care... NO! We are both enjoying the play with and without each other as we get to relate to each other later the 'play by play'.
The big O is not as important as the enjoyment of all involved. I try my best to find "that spot" with my partners so that they can have the big O. But primarily I want them to feel good as a whole. I pride myself on my sensuality as well as my 'technique'. Massage, tongue bath, caress, kissing, oral clitoral stimulation and of course penetration and finding just the best 'angle to the dangle' for the various 'spots' to be triggered.
My wife also just wants to enjoy what she's doing with her partner. When our partners are happy, we are happy. So far we have had partners that feel that it's a two way street and have given as good or better than they got.
As a friend of mine said... "It's all good... "
