actually, I just found another study consistent with that:

In the first study, Harris measured the blood pressure and heart rate of 43 women and 36 men as they imagined scenarios of their mates committing either sexual or emotional infidelity. She found that men showed a greater physical reaction to sexual infidelity, while women reacted similarly to both scenarios--with a slight tendency to react more like the men to the sexual infidelity scenario.

but the short term responses they were measuring probably don't match up well to longer term effects
