Why do men hide their feelings? This can be a rather complex issue, I say this because many men don't even really understand their emotional landscape if you will, this being said, when they do experience more complex and or conflicted feelings they aren't even aware of what it is exactly they are feeling, so with this in mind they are ill disposed to try to put those feelings into words. Now on the other hand if they are a little more well versed with their EQ (emotional quotient) and they are still concealing their feelings, this may be done out of a strategic reason, in that by concealing their feelings they feel they are better protected and more secure with their ability to control a situation. This can be the result of insecurity about them selves or perhaps a situation they don't feel comfortable with. Given what you have said, despite the fact that he says there are no feelings when you are having sex, he may very well still have feelings for you (yes even during sex). Realistically if you want to know why he is hiding feelings you have to ask him, which might be a bit of a challenge. Overall it sound to me like he has some growing to do before you find anything out from him in regards to what he is or isn't feeling. I hope this helps.
