Today my 18 year old boyfriend was a little afraid to ask me about this stuff that was on his penis, there is "pimple-looking bumps on the inside of his foreskin" he says he feels disgusting because of it.

I'm wondering now.. I have pimple-looking bumps on my inner labia and I'm wondering if it's just smegma or something else.. I just don't know the name for it. I'm also kinda worried, does it happen because I don't wash properly? Or.. 

I really want some answers.. and I really want to give my boyfriend peace in mind. I love him alot.

Note: me and him exchanged virginities.. we haven't had sex with any other people but each other.
