masturbation tips?

Fingering myself doesn't do anything for me and clitoral stimulation is iffy too. Sometimes I can find a spot that feels good but it's really hard to. Is my clit just not sensitive? Even when my man rubs it, I don't really feel anything and it doesn't really turn me on. I've used the bath faucet, which is alright. I have a vibrator but I don't use it very often because masturbation honestly just feels like work to me. I have a hard time enjoying it and it takes way too long to get off. Is this weird? And does anybody have any tips?
