If a partner is offended that you won't have unprotected sex, please get your clothes back on. Being willing to go to bed with you without protection indicates that he/she did that with other partners... Do you really want to sleep with all the people this person has slept with, and all of those people's casual partners?
Huff Post Live recently tackled the topic of midlife sex, based on a blog post by Marcy Miller, who wrote about being fixed up with a man named Fred described as the "catch of the century." After the third date, Fred told her that when in a relationship, "he expected to have sex 300 times a year," and this was why he had recently broken up with his fiancee.
