There is PDA, which we looked at with number 1, but there is also PDG, public display of getting it on, which makes us all a little uncomfortable.There's a chance your guy is fine with PDA, but what you consider PDA, he considers the kind of show people should have to pay for…in Amsterdam.
But I also think it's a good idea, if things are just starting, to give him some time.
Yeah, it's immature if he gets squeamish around his pals, but give him a chance to warm up to the idea.
How he responds to your taking of his hand, your hand on his shoulder, leg, or neck, can tell you all you need to know. Some guys are claspers instead of interweavers when it comes to hand-holding (for the record, I'm an interweaver).
Other guys think that holding hands is cheesy, or embarrassing, and they're more likely to go for an arm-link.
There is no moment, at least outside of the bedroom, potentially more devastating than when you go to grip his hand, touch his shoulder, or kiss his neck, and he moves away.
