The Kegelmaster benefits a female sexually for those having
unsatisfied intercourse after birth and in general having a weaker
pubococcygeus muscle (PC muscle). Seeing a gynecologist is the best
way to find out at what level is your PC muscle, four factors are
important (Control, strength, tone and atrophy). A gynecologist will
be able to determine if the muscle is weak or not. Biologicaly, the
source of the orgasm is the PC muscle. During an orgasm, the PC
muscle causes contractions. The stronger and healthier the muscle,
the better off one is to having an orgasm. During some child births
this muscle can be damaged. For some women that have never
experienced an orgasm, it is likely caused from a weak PC muscle.
Again the Kegelmaster is the best way to exercise this muscle because
of the resistance caused. Wheras contracting the muscle on your own
only helps to maintain the tone and level it is at, not improving it!

How much more, or how much harder the PC will be able to contract is
difficult to say in general, it is dependent per individual and
time. It will not be damaging, or painful to the male during
intercourse. Similar to masturbation, it can feel better when there
is tighter pressure applied, but only at an extreme amount of
pressure does it actually begin to hurt. Kudos for females in
purchasing this product, it will give you more control in bed. Have
no fear, the constriction a male will feel, will be frightfully
delightful.
