The answer really depends on you and your partner. Hopefully you are sexually compatible, and have sex drives that are reasonably close to each other.
Most of my adult life, sex 2-3 times a week seems to be the pattern, due to working, commuting, errands, etc. How much sex would I like? Daily, but that has only happened when I was was younger and we were on vacation.
The beginnings of a relationship also tended to be more sexually charged for me, so seeing a girlfriend for the night, meant sex typically when we went to bed, and again in the morning. Weekends? Usually 2-3 times. When living together, the average actually stayed the same, 2-3 per week, due to the reasons I mentioned above.
Now, later in life, sex twice a week is more the normal, but even just 1 time happens more than I would like.
Even as an older man, would I like sex daily? Yes, of course, but I am realistic and understanding of our ages, libido, menopause, work, life, etc.
