I would sleep around a lot
Why do you like sleeping around a lot?
I feel a huge urge to do so at a certain point.
It's normal to have sexual urges, but you shouldn't act out on all of them. You would be at risk of sexually transmitted diseases if you carried through with your urges.
I don't give a shit since I can't catch it...
You absolutely can catch diseases from sleeping around. You should reflect on your life and your moral choices.
