I think physical intimacy is a natural and wonderful thing. Many of us have certainly been deprived of it as our marriages crumbled and thereafter.
For me, it's a bit of a catch 22. I crave physical intimacy however I don't really want physical intimacy without the emotional connection. But I am not really emotionally healthy enough to connect.
Sex and dating is so different now then when i was single. I Was so young when I was dating my ex, that a lot of my ideas about sex are more relationship centered...still a big deal in my mind. Casual sex still is taboo for me and doesn't quite register even though I know it is so common and easy with dating apps like tinder.
