MW4M is one of the most popular sexual fantasies. The understanding that you are causing sexual arousal in two men at once makes women really excited. Men, in turn, are happy that they can satisfy and please their woman so much. Such a “chain reaction” makes people want threesomes even more. Also, MW4M is a great option for people who want to try something new in sex and play around with another person but do not wish to cheat on their loved one.
