Minnie sums up my experience well.
I dont want to be physically intimate with someone whom I am not feeling connected with.
Living with a partner who was in active addiction and even dry drunking left a big disconnect. I did not even want to be around him, much less be intimate physically with him.
Sex is personal to me. Although it has not always been, it is now and has been for a while. I cant muster up the desire to go there with someone I'm disgusted by.
I would much much rather be intimate with myself.
