Well most of the woman would be happy to be in your shoes. Having sex everyday with your husband can not be a bad thing. Sex is great way to keep your body in shape and it affects in a positive way every aspect of your life. Since you are in a monogamist relationship you don’t have to be worried about sexual transmitted diseases.
Are you using any type of protection or you are trying to stay pregnant?
Since you feel pain sometimes and sometimes you have vaginal bleeding this could be caused by rough sex. You could say to your husband to slow down sometimes and to be more gentle in a positions which are painful for you.
Anyway consult with your doctor about this. Maybe he can provide you with some useful advice how to avoid these symptoms in the future. Take care of your body so you and your husband can enjoy healthy sexual life.
