I think it all depends on your age OP and your relationship.
I'm nearly 60 and 3 times a day is just about acceptable. Although don't live with partner, but when we are together for a week on holiday, I still want it 3 times a day. If not more.
I was similar in my 20's but in my 30's with 2 young children working full time and a partner of 20 years, we were lucky to do it once a week. In my 40's with more time to myself and less exhausted my sex drive slowly crept up again.
I'm well post-menopausal and the relief of not being able to get pregnant made my libido sky rocket.
I'm happier with my body, well maybe not happier but more accepting, and I'm confident enough to tell partners what I want.
Sex is just getting better and better every year!
I remember in my 30's one of my friends saying they had sex every day and thinking "Poor cow".
Now I think "Poor cow" when a friend says they're not even getting it weekly.
As long as both partners are happy with the amount of sex it doesn't matter what everyone else does.
Also if you're in a long-term relationship and have kids and are carrying all the load, it's easier to feel resentment to your partner and that lowers your libo considerably.
