My fiance’ had a discussion about that earlier in the evening. She’s had all the fun she can stand after about fifteen minutes per session. The way I look at it, if she hasn’t orgasmed by then she isn’t going to, and she agrees.
She’s perfectly content to get off manually or orally and do four or five minutes. Rather disappointing now that I’m making headway on the multi-orgasmic front myself. But, in the end, I’m really involved in these things now to try to increase her pleasure.
Crap, I can happily go at it and blow in 30-60 seconds and be happy as all get out :D .
