I think I have dated the whole 0.01% of men that are fully capable of having sex 3 times a day and sometimes even more!!
If you have sex three times a day, that means 21x a week and 90x a month. The following is from a sex survey, the link is here:

How often do you have sex? Most men and women said they have sex once or twice a week. Yet, taking all their answers into account, men think they’re having less sex than women: Men said they have sex a median of 5.5 times a month while women said 8.4 times. Two percent of respondents in a relationship said they were not having sex, and another 2 percent said they have sex more than once a day.
You and your partners are certainly the curvebreakers! Most people will say 3x a day is excessive, personally I think it's doable, but really any more than that and I'd say the relationship revolves solely on sex and is a paramount priority. If you think having sex this often is normal, think again.
