Of course you can have sex without love. And of course, while H's W doesn't think so, love and sex go very well together and creates a very special bond between two people. I have a sister who has no idea what intimacy (sex) means. And she was married for 20 years, now divorced...to this day, she cannot openly discuss sex, she is far too uncomfortable with the subject. She is just not a sexual person, and even moreso, will not allow herself to be. I also think that many spouses who do not want to have sex are not feeling "romantic" love for their H/W; maybe more of a "family" type of love? Perhaps not in all cases, but in many. Sometimes that changes, many times it does not.
