I've haven't made love in over 6 years.

Everyone feels lonely every once in a while. I too get lonely when i think nobody loves me. Nothing is wrong with not making love for the past years so long as you have a reason not to. But if you feel lonely and you think you are ready to make love again, try loving someone again but you have to love yourself first since no one will love you if you yourself don't love yourself. I hope you find love in your life, and remember that God is there and that He loves you very much. Have a blessed day.
