Kegel does wonders for your sex life!
As for vaginal rejuvination, I'm not against the idea but its not for me
Alot of females that get it done have bore children and they are a bit loose
They usually make things even down there and tighten it and restore the hymen
I don't personally see a reason why if your happily married, it seems like a waste of money and time to me
to each its own
