Is it common to not have intimacy often.

We are married for 1 n half tears but we know each other and we’re dating for about 9 years. Only after getting married we had sex ( we didn’t have sex before getting married but we used to make out tho)

I just feel my husband is not into intimacy so much . Because he keeps postponing our intimate time and he fixes a schedule . I mean I don’t know when it’s a fixed schedule I don’t get turned on so much . I feel when you feel like doing it you must and not wait for a date , day or time. And of course he loves me a lot and I love him a lot too. But the intimacy is just not happening. Maximum we have sex 3 times a month . Is it normal?

I just feel very depressed due to this it’s hurtful
