Worried About Having An Orgasm With Boyfriends Small Penis

My boyfriend just left for college last month and we've never had sex yet. But he has eaten me out. It felt weird tbh.. I didn't even orgasm. The way he eats me out makes me wanna fall asleep.. 😂 Is that weird?
Also, he just sent me a dick pic and it's honestly smaller than I'd thought it'd be... He's like 6'1, I thought his "wang" would be a little bit more intimidating (around 8-9 inches).
When he comes to visit me in like November or December and if we decide to have sex, how will I orgasm? It looks like it's 4 1/2-5 inches. 
I don't wanna hurt his feelings.. and i defenitely don't wanna fake my moaning and such..
