Found Massage Oil in her nightstand - Is she cheating? Teke27

I found sexy lingerie and flavored massage oils in my wifes nightstand in the bedroom. Both items had been used, just not with me. When I questioned wife about this, she said she used the items to masturbate with and was angry that i "snooped". Several days later, the items were gone. I suspect she has been cheating. Your comments?
