I'm sorry you're feeling this low Weestar. I hope you can start to feel better soon and don't revert back to the dreaded weed. Look at how proud you were of yourself when you quit.
As for the porn thing, I'll probably shock a few people on here with my views, so I apologise in advance.
I always thought porn was nasty and dirty, and something for dirty lonely smelly old men. Same with any sort of sex toy. I was quite shy and restricted in the bedroom, and didn't really enjoy sex. Until I met my DH that is. He is very, very open about the fact that he likes to watch porn, and he has been from the start. I don't know what the difference is, but when he told me, it didn't disgust me, it intrigued me. He even has a women 'pleasuring herself' as his screensaver on his mobile, and he has even shown his parents, he is that open about it. He came home with a DVD one day not long into the relationship, and suggested that we put it on whilst we 'played' ourselves. It was a complete eye-opener for me.
He then bought us some 'toys' from Ann Summers online and we play together with them. They are not something that we ever use seperately, they are used when we are together. I went to Amsterdam on a hen weekend about 18 months ago, and spent over £100 in the shops over there!!!
He buys me sexy underwear which I love wearing for him, even though before I met him I would only get undressed with the lights off. The point I am trying to make is that we enjoy these things together, and on the one occasion that I have caught him watching porn on his own, it didn't disgust me, I just made a joke out of it.
Sorry if this doesn't help in your situation Weestar, but I just wanted to make you aware that there is an alternative, and porn isn't necessarily dirty. Some of the stuff out there is not my cup of tea, but we stick to what we know and like.
Oh, also I thought I better tell you that this has all stopped since I got my BFP. We talked about it, and both of us decided that we wouldn't feel comfortable using a vibrator while I was pregnant. It has all been packed away ready for the house move, and will be used again once LO is here.
