How much does sex hurt for the first time?

Oh, dude, it's like asking how much a tattoo hurts - it totally depends on the person. Some might feel a little discomfort, while others might not even notice. Just remember to communicate with your partner, take it slow, and use plenty of lube. And hey, if it hurts too much, maybe it's time to reevaluate the situation, you know what I mean?
