Don't be embarrassed I'd actually see it as a good thing that the girl I'm dating hasn't sucked a lot of dicks.

There's tutorials for everything on YouTube and I'm willing to bet there's probably at least a few on blowjobs but don't worry if you're bad at it, speaking as a guy that nots even in the realm of deal breakers. Just be honest and tell him you don't have a lot of experience with that so he doesn't expect to have his mind blown. Most guys are just happy to receive oral even if it's not the best knob slob.

Just don't let yourself be pressured to do it if it's not something you're into.

The only thing left to do is own it by doubling down and referring to her only as "mommy" in front of them. Bonus points if you ask her for milkies in ear shot of her parents.

Just out of curiosity if a girl lies about being on birth control to coax a guy into having unprotected sex is that rape?

Talking as a guy I think it's absolutely wrong to "stealth" someone. I also have a very hard time finishing while wearing a condom, it isnt that hard to say "hey I can't cum with a condom on is it ok if I take it off and pull out?" in which the answer has 99% of the time been yes. When the answer is no I just keep the damn thing on.

Doing something sexual to someone without their consent is a huge deal and it's kind of rapey to bait and switch with a condom like that and risking potential STD/pregnancy without approval just shows that he doesn't really consider your feelings and is a breach of trust.

This would be the same as a girl lying about being on birth control which to me would be a deal breaker.
