(TMI) I masturbated for the first time

im currently in a relationship and i told my boyfriend how i never touched my self sexually before because i always could just go have sex if thats what i wanted.(not in a hoe manner i was just always dating someone) So basically in my entire life ive never actually looked at my vagina either it was just there. im 17 and have been in many relationships and i thought some of my partners sex game was bomb but now i have to take it back. i dont believe i have actually ever had a orgasm till me doing it on my own. is that weird or does this happen to other girls also? do i tell my boyfriend that i masturbated or should i keep it to myself?
