This movie is in English and in color…pretty sure it is US-made.  It’s from the very late80s-mid90s time and I guess would be though of as a rom-com.  There are no big-name stars in it.

Plot is  – a somewhat bored married couple in their mid to late 30s are both pulled in the direction of cheating on each other.  They each find a willing partner. Husband finds a much younger woman, wife funds a slightly younger guy.  But when the time comes to cheat, neither spouse can go through with it. At the spouses’s home, the husband’s spirit is willing but his “flesh” won’t cooperate. At one point he says “I can’t do it . . how about that?”  The wife gets willingly stripped nearly naked by her would-be lover at his place but at the last moment she emphatically but somewhat apologetically tells him “I can’t…I won’t … I mean…I changed my mind…” Anyone know the flick?  Thx.
