Getting hard by telling others sexual things about myself?

I really enjoy talking to people and telling things like how big I am. How I touch myself, that if I want to.. I am long enough and flexible enough to suck my own dick.. I am 6'1" so I am pretty tall.. I am straight and don't think of guys sexually just enjoy myself.... Is i weird I like sharing things like this? Should i stop? I also like to Skype and show how big I am and sending pictures... I love geting feedback... I am a couple months short of 18 ..
