The "best" orgasm I can recall would either have to be when I lost my virginity to a yellow pit/lab mix when I was 18 or 19, or when I was finally able to successfully make love to my newfie girl for the first time. Seriously, with her height, and not liking any other position than doggy style, it was a friggin' challenge to make love to her. It took a whole week to figure out something that actually worked for us, and when I eventually did figure something out after 7 days of trying and failing, it felt like we consummated our "marriage" to one another. At the end of the success, I was so exhausted that I nearly passed out after orgasming. I haven't had one of those "almost passed out orgasm" for well over a year now. They used to be a lot more common when we were first figuring things out. But things have been figured out for a long time now, it usually takes me about 5 seconds to get in now.
