How much PDA is okay around his friends the first time

When she asks about PDA around his friends, she's not really asking about hand holding or where to sit. She's asking if you understand that his friends are his world and that how you show up matters. She's also checking if you'll make her second-guess herself or if you'll make it easy.

His friends will notice the basic stuff. Who initiates contact. Whether you two look comfortable or stiff. If you're on your phone or actually there. But they won't judge a single arm around her shoulder. They will judge if you act like she doesn't exist or if you're draping all over each other like you're alone in his apartment.

Your reply needs to do two things. First, tell her what normal actually looks like. Normal is being together without performing. That means small contact is fine. Sitting close is fine. A hand on her back is fine. Making out on his couch is not. This isn't prudish. It's just basic respect for shared space.

Second, tell her you want her to be comfortable, not cautious. If she spends the night worried about whether she's touching you the right amount, she won't be herself. Say something that lets her relax. Make it clear you're a team walking into his place, not two people pretending they don't know each other.

Send this back within a few hours. She's already thinking about the weekend and this is on her mind. A long message makes it weird. A day-later reply makes her think you didn't care enough to answer.

Don't follow up unless she texts again with a real question. Once you've told her 'normal is fine, I want you relaxed' or whatever your version is, you've done the work. If she brings it up again, she's looking for reassurance because she's nervous. That's a different move. For now, send your answer and let her sit with it.
