I started shaving very young an messed the skin up on my vagina and I still get bumps sometimes with puss is it a way for me to rid of those bump?

Stop shaving. It sounds like you may have chronic folliculitis. An examination is needed to confirm this. Usually this can be stopped by simply stopping shaving for a while. This gives the hair follicles time to rest. It is not likely that you have done any permanent damage.
