I'm not gonna give it all up, but if you smell perfume on your man, that might be an indication of something. If, when he or she disrobes and you can smell sex...!!! If you try to make love and they avoid all contact till they shower, if you see red marks on necks, breasts, thighs, if you notice panties or briefs missing, if they walk to the door rather than exit a vehicle in front of your home, well, you get the idea!
