Claws and masturbation

As the topic suggests I have some “claws” (longer nails than most). Basically I have a small discomfort with masturbation with myself but I am trying to overcome it. I was just wondering what is the best way for a shy 21 year old to figure it out without using your own hands because I tried that and I am pretty sure I cut my insides lol. Any help is appreciated. Thanks everyone
