Acting desperate is a huge turnoff for me. I don't care how handsome or nice smelling you are, if you are continuously dejected because life has not given you what you want (and you think you deserve) I would not be interested in a relationship/sex with you.

It isn't a game that you have to play to 'get' sex. Perhaps while you are working on your communication skills (sounds like you need a lot of work there) you should buy a sex toy or two. I have toys and they are fun and available when I want them and when I don't want sex the toys don't complain.

Good luck.
