Csab, it honestly doesnt hurt!!! make sure u get the purple BD needle heads, theyre the smallest one, 5mm, anything over that hurts me, there a spot about 5cm to left and right of ur belly button that it never hurts, anything other than that does tend to sting a bit.
Finger p!ck!ng hurts more TBH.
Hope that eases ur fears a little bit
