Ok this is an embarrassing question but... are any of you mommies feeling as un-sexy as I do these days?

I never ask questions like this but something happened last night with my DH and I am kind of heart broken. He went out of town over the weekend and last night we were going to try and have some "us" time in the bedroom. Well we started trying to get things going but then a series of unfortunate events came about. First our dog started snoring which made us laugh.... then I got one of his moustache hairs stuck in my mouth when we were kissing which also kind of hindered the mood. Before you know it he is snapping at me because I am taking too long initiating sex and he says to me "If I don't get things started then it'll never happen...." I was taken aback of course and tried to tell him sorry that I was caught off guard by our dog snoring and he just got irritated so we argued which needless to say put a end to "our" time. To me it was just a comedy of errors but to him he got annoyed that I didnt basically just jump right on him. I am relatively shy about that stuff sometimes and I do initiate but I guess not enough? It's mostly because I just do not feel good about myself anymore and I don't know how to get out of this rut. I feel so stupid and now I"m just flat out embarrassed.... how do I get over these stupid hold ups I have with my appearance and just get back to feeling like a sexy woman? I am not HUGE but I still have a little baby weight... I don't know why I am so hard on myself. I have always been this way and now since I am not in great shape anymore it's even worse. Any helpful advice or at least do any of you feel this way too? How did you get past all that ? I know this isn't a parenting question but I like you guys a lot more than anyone else :)
