One month you say? Hate to tell you but this dude is doing exactly what he'll do the entire duration of your relationship. Perhaps you should maybe think about moving on? With the exception of him disliking you hanging with your boy pals (which I understand even if it's more rooted in his insecurity than your behavior), your guy comes off as annoying .He's clearly very needy and that doesn't change. Needy people stay needy. It's what they do; hence, the term needy.
All you can do is ask him to stop. If he doesn't, well, like I said, it's only been one month. I'm sure you could get over whatever emotions you have wrapped up into him at this point. The only other recourse is to argue with him about it, which I imagine would have the opposite affect you want. He'll probably get his feelings hurt and say something like, "I'm just showing you how much I care about you" which will then make you look like a douche and you'll end up being clingy towards him for a while as he licks his wounds, which will allow him to be clingy again which will just repeat the cycle all over again.
It's really a no win unless he realizes and accepts that it drives you batsh*t. So yeah, either he cuts it out, you deal with it, or you part ways.
Thanks for answering my question! I had a long conversation with him the other day about how I was feeling and he was aware he was being overly clingy, and since then he has tried his hardest not to smother me. I do really like him, but I think you're right. I'm going to give it another few weeks and see how it goes. The thing that annoyed me the most was when he would stick his hand down my underwear when I was trying to watch TV/read a book. Even when I told him not to, he would try again half an hour later! I just found that incredibly disrespectful.
