Update:
Last night while I was at work she started sending me provocative pictures. I said I am going to smash it when I got home and she replied back "how about I go out and get fucked first and then you fuck me when I get home?". I of course accepted that offer. Feelings of inadequacy are fading. She went and played, When she came home and told me about it, we had amazing sex again and I made her juice 4 times myself which helped with the inadequacy feelings. She said this guy wasn't as well endowed as the first whom she nicknamed "king cock" but that he was adequate and she squirted for him too. I really feel this is helping our marriage. She actually seems to be able to keep it just about the sex with no emotional connection, I attribute that to the alcohol haha. Over all it's been great so far. She seems more open with me too now.
