Hi cherryblossom15,
Many people enjoy sadomasochistic sexual experiences. It is okay if you get excitement and pleasure from your husband hurting you in some way.
If this is an area you want to explore further, I think you should read more about BDSM and safe sex practices. If you're going to play rough or draw blood, you want to know how to avoid serious injury and infections. You should also make sure that at any time either of you can call for the activity to stop in case it gets too intense or painful. (Some people decide upon a 'safe word' for this purpose.)
I don't think you have anything to be ashamed about. If all your activities are consensual and you are not allowing yourself to be hurt because you don't think you deserve to be loved, then I think you should enjoy it!

Explore your kinky side, especially if your husband is also interested. If you're keen, maybe join the
FetLife community to join discussions and share tips with like-minded people.
No diagnosis, lots of opinions, and a bunch of issues that I haven't quite figured out.
