Tickles while I masterbate ...

When ever I try to masterbate I rub my clit and I start to get wet and work myself up and then my legs start to twitch kind of and I keep going and then I rub it faster and faster and feel it start to feel better and better and then my whole body like tightens up and it's like I ball up because my muscles do what they want, anyways after I make myself super wet, I can't even touch my own clit anymore with out it tickling so much! That's when it no longer feels good, it's way to ticklish down there after a while. How can I stop it ? I feel like it's stopping me from reaching an orgasm because I stop when it gets too ticklish.
