Sex is so much about communication, and you want this girl to be good at what she does. Some guys don't mind it, but others do. Some girls don't have a lot of training in this kind of thing, so you need to communicate your preferences to her. So to get her to open her mouth, you have to open yours. Men are not taught to wait for sex.
Women are the gatekeepers of sex.
There are some men that are not comfortable jumping in the sack with everyone though. I think what the people are trying to say is they feel a fondness but the passion is gone. They are trying to let the person down easy I guess. Being in love and feeling in love is kind of synonymous. Love is something you do to someone.
