Should i send someone dirty pics?

theres this kid i've been talking to that goes to my school and were kinda friends. he asked me to send him topless pics and i was like ummmm no. and he kept asking so i said maybe with bra and underwear on. he said he swears not to tell or show anyone. but im really not sure if i should do it at all. i feel like im disrespecting myself. and what if he shows someone?
