1) Manscape
2) Make sure its not cold outside - no one likes a turtle
3) If showing your socks while taking the pic make sure they are clean
4) The carpet in hotels is sometimes very obnoxious please keep that in mind
5) Its all about the angles to guys think about it and make sure your unit is bigger than your hand if its not just say no and save that little disappointment for the bedroom when its go time.
I know these little hints seem harsh but take heed boys I have gotten enough to darn near be an expert at this point. And please if you feel the need to "show us how much you get excited when you think of us" don't send it right away at least wait until you meet us in person - no one likes false advertising so meet up first then decide if JR feels the same way ok. Ha this more more like a public service announcement today you are welcome!
