Gods yes! See someone – that does not sound right! I know there are always two sides to a coin, but .... from what you saying – he’s got it all and you!?
Before that last remark about what you are forbidden to do – my suggestion was going to be: maybe you can both agree to find someone suitable to join you in your erotic play. You can still satisfy your husband while you can have someone else take care of you in your husbands presence and with his permission – giving him the full ownership of you and your pleasure.
but... i don’t know – there obviously are hurdles you need to overcome – and if your marriage is as important to you as you imply...
good luck - you are going to need it sis!
