Bad Head? Or bad sex?

Nia

So, my boyfriend and i just got sexually active about two months ago, and I’ve given him head probably a total of 8 times. When we have sex, he always cums, but when i give him head he doesn’t, however he always moans when i give him head but he barely moans during sex, im confused but I mostly think he’s faking the moans and doesn’t wanna hurt my feelings. 😂🙄
