My boyfriend doesn't seem to realise what he's doing? I don't understand blokes! (ually frustrated)?

Sounds like you have a cuddler. He likes to cuddle and he's happy with that. He likes to frustrate you too, which I can understand being a guy... I don't understand why he doesn't eventually help you. Now, if you're a nympho you might want to invest in adult toys or something. Maybe that would change his attitude... some guys like watching this. Other than that the only thing you can do is talk to him. I mean really talk. Tell him you want him to follow through if he's going to warm you up.
