If a man chose to not finish during sex, would it give him more control of the relationship?
Not finishing repeatedly (if the partner cares enough) makes the person feel like a failure, which with enough times is likely to make them less enthusiastic about it.
Finishing last however and going that extra mile to make sure she's finished instead of just sated seems to work well enough (unless taken for granted).
Excellent point. I was thinking more along the lines of stopping just after making her finish. Totally put on an act like it was awesome for me and all, but I just never finish.
Someone else already made the point women have done this forever and a day. This would be an interesting study if someone were to try it with a new target. I have done it, but I only have my own results.
