Feeling love.  You can just feel love and that's great!  You can also use your chakras and love.  I use my Root Chakra and feel love being created.  I feel it moving through my body and out.  the root Chakra is the creative source.  You create love and feel it moving through your body.  It is a very powerful feeling.  Feeling that feeling of love in that area is much better than obsessing about sex.

You don't have to feel love for someone as a matter of fact it's probably best if you don't.
Just feel love. If nothing else,  just doing that will change your life for the better dramatically.  When you feel love you raise your vibration to the level of Love.  The level of all healing, the level of all good.  So if you want healing, if you want good in your life feel love.Feeling love you can feel a connection between you and the other.  If you feel love for someone or something it creates attachment.   Attachment isn't bad until you have to detach  then that might involve pain.  Having a connection is, I believe, much better because when you disconnect it's not as painful.
