So did having to remember all this stuff get in the way of your having fun?

The last sentence is interesting. Certainly vaginas and penii are very different but they are also formed from the same tissue, with correspondingly similar nerves, and have a number shared purposes, namely getting off. Using "stuff" is like saying "people" - it's a term you use when the difference isn't important and in fact looking for differences is just confusing.

Oh, and as usual, you totally rock.
