Peope who stray will stray because that is their personality. Nothing their partner did changes it. Or they stray because they are dissatisfied and their partners are not willing to work with them in any way at all. You cannot blame yourself if you partner strays if you tried to work things out and meet him/her half way.
About not enjoying penetration, well you can read a lot about that on this board. Penetration is not one of the best parts of sex for most women. G-spot orgasm just isnt' want great for me. Having clit stimulation with penetration is what feels the best. Each woman is different. There is nothing wrong with having your own desires and preferances.
Regarding counsellors, you really have to shop around. Each one in trained on different theories and beliefs. You really have to find somebody that works for you. You also have to believe in it. If going to support groups helps, then use them. If talking on these forums works, then do that. You need to find what works for you. Don't give up. It is sad, but there are many survivors of sexual abuse. They have found a way to over come it. You can too.
