emotional rescue.
it's easy to understand with the cold fish husband you have and scott studly walks into your life, you'd be a little taken back. you state that he doesn't care about sex. you state that he's a workaholic. the miscarriage situation was the catalyst that put all these negatives in force, and your hubby was the lucky guy on duty during this period. now, you obviously want something he can't give. seems to be a normal reaction to the situation. you do realize if you go and screw this new stud you'll end your marriage, even the good parts of it. so with that in mind, it's easy for an outsider like myself to state confidently, "don't lust after the dude". but i suspect that deep down, since you "connected" and all, this guy has taken the place of your husband in the category of "lustful thoughts". now, you're left with a paycheck, some good normal marriage times, and not much more.
for whatever reason in life, men and women are usually confronted with temptation. there's always one good attempt at breaking up a marriage. and this one might be yours. the ones who pass on it, keep the status quo. the ones who act on it, typically find it rewarding short term only to really be confronted with a mess later on. your call. you have to live with yourself. are you the type that has a conscience? do the positives outweigh the negatives in your marriage? only you can determine those facts. we don't live with your husband. just remember this...very, very few quickie affairs end happily ever after. you're dealing with two, basically new to each other personalities and desires. your soulmate on the other end has an opinion as well. as i counsel many in your predicament: everything has a trade-off. good times in the sack now might lead to intense, emotional upheaval in your family later. is hot, fiery sex now worth the potential firestorm later? maybe your present husband wasn't "the one" you thought. think it through before you take off those panties for another...
