I would like to do them but want to know how to do them correctly and how many minutes or seconds do you hold it when contracting the muscles coz it doesn't hurt but can get a wee bit painful. I am seeing my hubby in 2 weeks and want him to enjoy me. How often do you do them for to get really tight. I think wee is leaking down there as well because my panty-liner is getting full (embarrased)
