I prefer being part of a couple, but when I was single, I enjoyed myself.
I do not feel restricted or limited by being in a monogamous relationship. I feel freer to be myself, and express more of myself. I don't mind passing by a crowded club on my way home, because that's so not my scene. If I pass a crowded bar, that might be a place I would like to check out on my Honey's arm.
I wonder why when people ask this question there are always these extremes put on it. My husband I do not stay home all the time (we love the beach, movies, restaurants, other people's houses). When we are home, he watches a TON of TV, but I don't like television, so I do something else about half the time. I love that even this far into our relationship we tell each other "I love you". If I want to go out with friends, I do it. If I want to do something lone, I do it. He's my husband, not my warden. Toward the end of my single life, I was definitely tired of being single, and looking to meet my someone special.
When I was single, I enjoyed meeting new men, and exploring them as people and sexual beings. Now I still meet new people, I just don't explore them as sexual beings. I prefer to meet people who are in a couple as I am, because that's less awkward for them. I'm in a saccharine sweet relationship, and most single friends get a little sick of the cuteness. Also, single friends often want to do activities that involve being available to meet new men, and that's just not where my life is right now.
