Girls have the better deal

kikilizzo nailed it. Life, Romantic Partners, and Marriage is about a lot of other things than sex (once you get past the juvenile stage in life).

However, from a sex side most guys can have at least 4 sex sessions per day, and can ejaculate at least twice each sex session (some can ejaculate 3 or more times per session).

While not as many orgasm's than a woman can have in a day... Isn't that enough sex in a day.

I have found that a good sex session takes at least 1 hour and often 1.5 hours from foreplay to after sex cuddling (independent of the number of orgasms both the male and female experience); and for woman its the kissing, cuddle, and talk time that is at least as important as the actual sex itself.

Finding time for that much good sex with all the other things in life is more of a problem than having willing partners, in my experience.
