That is actually a very good point, and is necessary for keeping in mind male multiple orgasms. I've seen guys have more than one orgasm, where they ejaculate for the first one and then are so horny they can be made hard again and then orgasm again (but nothing comes out; they're empty!) I forgot about that.

My little one could never do that, though; once he ejaculates he is usually asleep like the dead (maybe I work him too hard ).
