I have been the first provider for more than I can count. That number goes up weekly lol
I have been the first sex for a few. Most memorable was an absolute sweetheart, years ago, that booked me for 24hrs because he was about to enter into an arranged marriage. He wanted to learn all he could so that he would be able to please his new wife.
I have been the first greek experience for at least a dozen. I enjoy it most in doggy. Least in CG.
