We cuddled whole night but didn't have sex... anything might be wrong?

I have a boyfriend with whom we just recently started to have intimate relationship. We usually manage to meet up twice/thrice a week, so it seems like we would want to take advantage of that time. However, last time we met, he just asked me to lay with him in bed and we spent whole time like this - caressing, massaging, kissing, talking, laughing, everything in a very relaxed and cheerful way... but he didn't really show any willingness to go beyond that. Might this be a sign that he doesn't enjoy having sex with me? Or it happens with guys sometimes that you are just not in the mood to do things???? The reason i am asking is that he is my first man, which means i am not that experienced in bed, so i thought this might have put him away? This is the first time it happened, but i am not sure why, maybe it might have been better to ask him directly if anything was wrong? - -your feedback will be much appreciated!
