Orgasm feels like being tickled to death

Nicole
I've been sexually active for 6 years and have never orgasmed, be it with my husband or on my own. When I start getting stimulated (internally or externally) for more than 2-5 seconds straight, it always feels like I'm being tickled to death and I can't handle it! And not a sensual tickle either... more like an unbearable death tickle! 😕😬 Is this normal or totally weird?! I have no idea because I'm pretty sure I've never orgasmed.
