I don't think you should be worried. You've been going out officially for three days, and it makes sense to me that you haven't gotten that physical yet. Talking about getting intimate is definitely a conversation that you should have with him, but maybe not right now. Since you're both shy, it wouldn't hurt to initiate cuddling or longer kisses.

Nothing to worry about, you have only been together for three days. Some people start to have sex when they've known for two weeks (or less), others when they've known a year. Even if you two didn't want to wait, you still don't need to start having sex after only three days - nothing wrong with that, of course, if you both want it, but three days of dating really isn't a long time and in my opinion wouldn't even be counted as "waiting". :)

Have you talked about sex at all? He might be shy, but he seems to be alright with talking about sexual things. From what I've gathered, he just wants to wait a bit more until things go further, but you still have to ask him - it might be that he thinks you want to wait. Communication is the key.

And it doesn't have to go straight from pecking to sexual intercourse, remember that. :P

No problem. Hope you two lovebirds have fun ^^

I agree that you shouldn't be worried! Pecking is pretty normal after only 3 days. I mean, every relationship moves at it's own pace, but I'm sure yours will progress continually (: if you have this problem a few months down the road and you guys aren't on the same page, then it's definitely worth talking about! But until then, I would just try and relax a bit and enjoy things... he even said you make him nervous, which is a good sign that he could just be waiting for the right moments to make a move.

I'm going to echo everyone's thoughts--it's only been three days, don't worry! Maybe he doesn't want to move too quickly in the relationship. Or perhaps he doesn't want to give off that "I want you for the sexual things" vibe. Your relationship is still fairly new, and as you've said, you make him nervous in a good way. Perhaps he just doesn't want to mess anything up, or doesn't want to make you uncomfortable!

He may feel more comfortable after you two have conversed over the subject. Or perhaps things will happen given time and the right circumstance. I wouldn't worry about him becoming bored with you, though. It seems like you two are off to a great start! Good luck!
