Does he only want me for ?

I was talking to a boy i liked online. we were on twitter so he say RT if you want a honest DM so i Re-tweeted. Then he said 'you're some skin, i like talking to you you're pretty cool funny and if you'd let me no lie i'd f*** your brains out'. i was shocked so i didn't know what to say so i was said 'WOW' then he said ' Isn't that enough okay i would put you on my shoulders and lick you're from the back' and he said more X-rated things so i said 'can you stop please' then he said 'im really sorry i just really like you and doesn't really matter to me i'd only have it with you if you wanted me to'. Should i carry on talking to him?
