Is something wrong?

When I masturbate I normally just play with myself as far as rubbing the clit until I reach orgasm. But as far as fingering my self it’s so uncomfortable for me.. it doesn’t feel good it feels like nothing is there literally and when it first goes in it kind of hurts me.. irdk if this is a problem within myself or what.. sex never feels good for me unless it’s doggystyle and fast.. other than that I can never feel anything.. anyone else? & what are some tips that you can provide to help masturbation fun?
