How often do you have sex? Omg 😲

I have been married 3 years and with my husband for 9 years! We have 3 boys together ages 7 5 and 11 months! We are young 25 and 26 i feel like we dont do it enough I Google some ppl say 3x a week im lucky if I get some 2 or 3 times a month! It is hard with having small kids trying to sneak off without them being nosey and his schedule for work is always diffrent we dont make enough time for it when im in the mood hes tired when he's in the mood I cant get into it bc the kids are awake and I cant relax knowing they are awake and everything. At night is my favorite time to do it but he gets home and is to tired and when he's off of work we usually have some time but its rare. Idk I feel like we are young and should be banging more lol wby mamas? I need more 😩 🤣
