My hubby and I had excessive sex for 6 years. Any demerits? how to overcome this? Any medicines/natural food?

I am married at earlier age. I and my hubby started having sex when I was 21 and my hubby 23. Now I am 27 and he is 29. My hubby daily sleeps with me for the past 6 years. We use to have sex twice sometimes thrice on holidays, once or twice during normal days. We did these for 6 years. Will it affect our health? Shall we continue this? If it has any demerits how to overcome this? Any medicines or natural foods? Plz advise me?
