feeling sexually frustrated

So I was tryin to hav sex with my boyfriend because we haven't done anything for a while due to me having too much pain on my back because I'm pregnant but anyways .... I started to go down on him n giving him kisses n them I wanted to do something more n he completely shut me down .. all he wanted me to do is continue giving him head until he finish so I just got up n was lik hell no u can finish on ur own then ... which he did n he literally just knocked out lik r u kidding me .... should this hav bug me as much as it did ??? Or am I overreacting ???
