I don't believe these women can keep going -- they are like a man in that when they get there they are done. Continued intercourse can be painful for them.
My comment was in jest, but in my experience, different women, different capacity for pleasure.
If this can aid them in completing the experience when they couldn't before, I'm all for it.
Hopefully it won't lead to the same abuse that the standard viagra has.
I have read about women who subject to pain during the experience. Talk about negative reinforcement. This would be a blessing to many if it helps.
