Set aside your embarrassment and be honest, I’d say. I doubt any guy would be uncomfortable for that fact alone. And if they do, well, bullet dodged! Like others have suggested, you can always look it up online, try your best, and have fun with it (which is the point anyway). Plus, after you get the first blowjob over with you won’t have the inexperienced label anymore. I actually looked it up briefly online myself, told my now long-term boyfriend I was incredibly inexperienced, and then when i actually did it I was told it was great lol. So you never know!

But if it’s not something you’re comfortable with, don’t force it of course.

Best of luck!
