Patient: Alrighty. This is quite embarrasing.The other day i was masturbating, i guess it wasnt lubricated enough and it hurt, so i stopped.Now my vagina has been hurting for two days, so i decided to check what it was. I seem to have either a bump or a blister in my vagina! I haven’t had sex in 6months, so im pretty sure its not an std but… Im still doubtful! Is a bump in the vagina common after masturbating while your vagine is not lubricated!?
