Me (19m) dating this girl 18f) we decided to spend the night at her place and after I made her finish she started going down on me and while we were at it she gave me a handjob at first and then she started massaging my balls slowly which gave me intense pleasure so much so that I almost came close to climaxing, idk as this was my first time w any one and having the feeling for the first time, I mean! haven't heard or read anyone having such reaction by just massaging balls, is this normal n if it is how can I initiate it more??
