Men's opinion here... first wife liked it, but I always had to initiate it. Second wife was definitely addicted to it. She said that she loved it because she felt like she was in control. She was very good. We swung a bit, and would get many compliments from couples we would party with. I would come home from work to her nude on her knees waiting for me, and devouring my cock sometimes in the doorway. Third wife did a lot, before she became disabled.
Current gf will meet me nude but, pulls me to her bed. She also loves to suck my cock. I know that she is addicted to sucking my cock.
That said, I have enjoyed sucking cock myself. Haven't had one for a very long time, and find that I would like to enjoy one again sometime
