Even if it was terrible, you might have learnt to never got to that restaurant again, that you can get through 4 hours sober, or that you have a fantastic funny sober dating story to share with your friends.
A bad date is not the end of the world, but a learning experience to help you for the next (better) date.
And sure, it can seem a lot easier to skip the awkwardness when you’re a little drunk, but on the other hand it can make sex worse.
On a purely physical level, alcohol screws with your sexual function.
On the one hand, do you announce it as part of your online dating profile in order to weed out those who would just not be accepting of that? There’s no one answer, and ultimately your dating profile should be true to your identity, and only you know where drinking fits into that.
If you’re really nervous before the date, have a bath or a massage, chat with a friend or go for a run.
And, believe me, no one is going to scream at the sight of your naked body.
