So your explanations for why men might have more sexual relationships than women on average is flawed, none of those reasons would change the averages. Imagine if you had 5 men and 5 women, where 1 man had a sexual relationship with all 5 women and the other 4 men had no sexual relationships. The average number of sexual relationships for women would be 1, because each has a sexual relationship with the one man. The average for the men is : (5 + 0 + 0 + 0 + 0)/5 = 1 ! So whether or not there is monogomy, or different patterns of behavior, the average remains the same. The only way the two numbers could be different is if you included same-sex relationships, or if there were more men than women (or vice versa).
