Using a Vibrator to Make Sex more Exciting

I just want to make a quick yet crucial clarification.
Vibrators are a turn on during sex when you use them on YOURSELF. Please do not get carried away.

Also, thanks Indiana University for this useful and informative study.

Turn Him Into Man Mush

I agree that a massage can be a huge turn on.. however I'm not sure how additionally horny boosting my immune system makes me. Since when did flu prevention became an afrodisiac let alone any type of motivation for a sensual massage? I am also not sure how effective lube will be in the shower.

That being said, you had me at "Man Mush". A massage in the shower can never be a bad thing. If boosting his immune system serves as some type of motivation then so be it. I am really just looking forward to when they find a sex position that may help prevent cancer.
