I read your blog last Thursday from Peter Perplexed and I am not sure that you can just be in love with one part of your lover. It doesn't seem to be very mature.
I know, I know. But of course sex and love are not very mature. And perhaps if you only love one part and the rest of him is just no, it will inevitably not work out. But the rest of him might be fine. I do think you need to be hung up sexually on someone to really love them, otherwise it is just roommates with a little sex thrown in. And I find that immature.
