It wasn't ok, he sure wasn't happy with the pair of you being in a relationship, together, going on holiday as boy & girlfriend, and NOT being in a sexual relationship. If you thought such an arrangement is normal for a young guy, you are likely mistaken, and need to discuss this with the next one you meet with.
I'm not excusing his actions, but I think you need to expect that a guy in an exclusive relationship with you is likely to expect that the pair of you will have sex.
