thoughts from another newbie
it sounds like you have a lot going on and i need to ask... is it really fair to your long term partner to be going on in this manner behind his back? you say you are commited to him and yet you are flying across the country to be with another man, that's really not very commited and it's downright cruel. if you want your Amo then both you and he need to sit down and consider the other people in your lives for a few minutes and decide how you are going to break up with them. it's not fair to your partner or his to continue sneaking around behind their backs in such an illicit manner and in the end you will end up hurting them both worse then if you simply sat them down and said you wanted to leave.
the other thing you should think about is whether it is really your Amo or the D/s style relationship that he is offering you? i'm new to this lifestyle myself and find it to be heady and almost addictive at times even just thinking about it. and just a thought but since you say you are commited to your partner there is always the idea of drawing him into your newfound interest in D/s. the boards are full of couples that discovered D/s together and are quite happy for it.
honestly i am not trying to be a bitch even though it might sound that way and i apologize if you take offense to what i have to say feel free to disregard it utterly if you like.
