If you have doubts and insecurities about whether or not he only wants you for that, you should be direct and ask about it. Everyone sees sex differently, maybe for this person it is something more casual with no feelings attached, but if you think it'd do you harm to just do it, dont try to force yourself.

i really afraid of that not because of physical relationship .im worried he just want me only because of sex and had no feeling for me
