Help😩

Okay so when my and my SO are having sex I'm normally quiet, which I know I'm enjoying it but I feel like my SO thinks he's not pleasing me😕 honestly I'm not a moaner, he'll get a quiet one here and there but I'm just not loud.. And he likes to dirty talk and I just get uncomfortable lol.. 
What can I do to show him I'm liking every bit of it without going full out porno moaning😂
P.s. I usually kiss his neck, or bite my lip
