Handjob secrets?

So I have a problem with always playing with my SO penis.. mostly at night if I can’t sleep or if we’re watching tv. You get it.. I never see him like close his eyes or do a small moan unless he’s ready to have sex. I’ve asked if I do okay and he says “I love it” but I feel like he’s just making me feel like I’m doing fine. I’ve seen him masturbate couple times he squeezes hard and goes really fast. I can’t squeeze hard cuz I feel like I’m hurting him. Plz help me and any advice or tips. Thank you

Btw he’s uncircumcised
