No, if no sex then you must be alone and nobody wants that, why are we here? I thought sex was making love to your partner. Happy is being in love.
Some people are here because of the forums, not to find a relationship. No sex doesn't necessarily mean you are alone, you could be in a relationship where it stopped for some reason, as Igor pointed out.
Making love can include sex, but sex isn't necessarily "making love" to everyone, sometimes it's just the physical act of having sex.
For me, I am not in a relationship, and I am happy, so my answer is yes!
If I were in a relationship, my happiness would not be contingent on the person I was with. With that said, if the closeness we shared were to suddenly stop, I would want to know why, reevaluate my relationship, and decide if this new arrangement is something I can live with. Sometimes, there are medical reasons sex would stop, and in a loving relationship, couples can still be happy because that isn't all that matters.
^^^ What She Said!
I try to remember that happiness is an emotional state rising and falling from the standard of contentment. Associating sex with happiness is dangerous. Sex can also be painful and oppressive.
Contentment allows you to experience happiness in many ways without sex.
Sex can be an animalistic urge to be satisfied or it can be a wonderful expression of love for another. Both can make you feel happy but sex is not the only thing that causes happiness.
The lack of sex can make you unhappy and discontented if you focus on sex as a marker for happiness. An unrealistic emotional projection.
