Do I really have to give my boyfriend blow jobs?
You're not obligated to, are you mad or upset over something?
He pissed me off.
If it take denying him blow jobs to correct his behaviour, them that's honestly a small price he's paying. He should be thankful to you for being so lenient.
It's not that hard to be a good boyfriend- it's just one blow job!
I understand where you're coming from. You made the first step the setting an example, but I would recommend mixing in some communication on why this is the case.
