Okay, I'm going to give two prespectives here. I'm actually sitting here reading this with my "guy"... He'll goes first, because men are impatient :)
From the OM:
Mid 40's
2nd marriage (13 yrs)
1st affair (on current wife)
My OW and I have been at this for a while now and so many things have changed since we started. I'll let her tell you about our history.
It started off where I was still intimate with my wife, though like most of you it wasn't the same as with my OW and not nearly as satisfying. At first it briefly kicked up my sex life at home, but it was VERY short lived. Our sex life was dead to begin with so the extra interest on my part part was quickly killed and things went back to normal fast. Now, almost a year into my EMA my OW is pretty exclusive. I honestly can't even remember the last time I had sex with my wife, nor do I care to try and remember. Yes, ladies, it is a need that a man has... But, I suppose the need gets less and less when you have someone else in your life like I do now, someone whom I care deeply for whole heartedly in every aspect.
I wouldn't take it too personally and there are a lot of good points being made in this post (and some just make you go hmm). Men think differetly than women, period. Yes, it bothered me knowing that my OW was intimate with her HB, but I didn't dwell on it and I honestly got a little turned on when she talked about it. And sometimes, us men just want to get a response out of you when we tell you things *wink. Sorry ladies, but sometimes we do... I now know that it wasn't a very nice thing to do, but my OW actually admits that it turned her on at times as well. However, I have much more of a connection with my OW than I have ever had with anyone so perhaps I do have it very good. Don't tell her... But I can't live without her.
Good luck!
Okay, now from the OW:
Mid 30's
2nd marriage (9 yrs - now separated)
1st affair (on current HB)
I had to walk my OM to the door as it's time for him to get on with his day :(
So as far as intimacy goes, I was in a little different place than my OM when we started. He really isn't the other man anymore because I am now separated from my HB and we are getting divorced. So, I've become the mistress in sorts, lol.
When we first started I was struggling with keeping my marriage together as it was troubled. Plus, we were facing a relocation. My OM actually helped me, temporarily. We were/are great friends, even if it is at times hard for us to give eachother whole-hearted SOLID advice, as friends. But, I suppose that's what makes it as good as it is, because we do...
We never really discussed our spouses much, in the sack. We didn't have the need to really. I wasn't satisfied and neither was he! During our times apart I did cave several times with my HB but I often found that a few glasses of wine were needed first and sadly, it wasn't to benefit him at all. My marriage was over, I knew it. I wasn't going for anything, I just had a need (which most women do at times believe it or not). Eventually, my HB relocated and I did not follow.
However, I am not the jealous type either. I could care less if he has sex with his wife, really (I know they hardy do anyway)! And yes, he's right about us "telling eachother" about our spouses... I suppose though that were are both secure with our own selves that it didn't really matter to us. Of course I don't like to think about it, but I certainly don't let it bother me. It is what it is and it's an AFFAIR! You have to share! If you can't do that then you need to get out of it...
I think you just have to think about what you want out of your EMA. YOU need to figure out what YOU want and what you can/can't handle. Can you mentally balance two separate intimate relationships and remain level headed about it all? Can you live a double life? Are you willing to lose it all if you get caught, or at least deal with the consequences? What about pregnancy or STD's? Have a plan, be open and honest with your OM/OW and go from there.
And as far as having sex with your Spouse... Wine and lights off!
To touch on contraceptives... ALWAYS! If you're a woman, go on the pill, shot or whatever. Men, wear a condom if you can't be sure your OW is protected! Trust me, been there... You don't want to go through it, it is VERY painful and benefits no one. An unplanned pregnancy places a HUGE strain on everyone involved, no matter the outcome. Not to mention that STD's are always going to be out there and there is NO way to know WHO has one usually until it's too late. Thankfully, I don't have to worry about that but you can't ever be too careful.
Good luck!
