its ok Gentle. edging is when you jerk till you get close to cumming "on the edge", but then you stop. the longer you continue on edging, the greater your ejac feeling.
the answer to kegel exercise is yes your ejac is more intense and can shoot further with the increased strength, it will also give greater erection hardness and longer hardon ability.
i once edged for 24 hours and while sitting on the floor and was able to hit the ceiling awsome feeling of release. careful though other times i have edge for over 20 hours and have had such bad nut pain it took for ever to pop my seed the release hurt like shit too.
