Did My Parent's PolyCotton Sheets Give My Boyfriend Scars? -- Good Questions

Q: My boyfriend and I visited my parents house last week on our vacation, and he found himself getting - ahem - really bad burns on his knees after a few days that even bled and stopped our lovemaking in its tracks. We've never had this problem before in our own home. My parent's bedding is all polyester/cotton blend. Is this the culprit or were we just more randy than usual?? Sent by BklynGirl More
