Am I reacting over nothing?

I live in a house with a few other people and two of the people i live with have girlfriends. Naturally, they are intimate. Whilst one couple are rather quiet about it, the other is not. they screw constantly, like bloody rabbits and quite loudly - even when i am watching tv or in my room i can bloody hear them.

is it unreasonable for me to speak to them and tell them to keep it down? i do not know about others, but i consider it unbelievably rude and inconsiderate.

any advice?
