Growly I commend you for being so brave! And it's great he responded how he did. Even though he didn't say out loud that he cares about you, it's obvious from his reaction and his suggestion of an extra winding down session that he really does care about you.
I just wanted to say about the whole 'not attractive' thing, and I hope this doesn't sound like trite, my experience is that when you find someone with whom you connect on a deeper level, looks are not important at all. You are intelligent, funny (and I bet your self image doesn't match that which others see). You are so loveable and it would be a shame to exclude yourself from trying to form relationships based on your own idea of what others want in a partner. I don't know whether dating is right for you or not at the moment, but if fear of rejection is the only thing holding you back (which I can totally understand by the way!) it would just be a shame to deprive yourself of an opportunity for happiness based on what could be a completely false assumption.
I hope Kashi works out for you and that your last couple of sessions with Sparky go well
