Mental is where it's at. The girl I'm with now is the greatest woman I have met in my life. Because I like her so much I get caught up on my thoughts, and at times can't muster it up
She tells me it's ok and when it goes it goes and she loves it. Eventually your nerves well settle and the trust with her will bond. Remember it's been a year, you may feel like you have to make up for lost time or that you still got it. That thought mixed with doubt can really be a turn off for you even though you are in the mood. I feel you man I am still going through it with my girl, but I find that when she is really hot from all the forplay and my mind is only into her, my little buddy is ready to go. Just took time for me to clear my head.
