I don't like Lycra anymore, but a decent pair of mountain bike shorts ($45 or so on sale at places like REI) provides support without putting you on display. Or you can buy cycling underwear (Andiamo and Pearlizumi are two good brands) to wear under street shorts.
Finally, make sure your saddle is level or nearly so. Occasionally I see people riding with the nose pointing up (?). That will smack your johnson for sure.
What Velo Dog said. I only ride with Mtn Bike Baggies with the support on the inside. Some times a readjust is needed, to the left & forward position. And, he is spot on about the seat angle. I have seen as little as 1/8 inch tilt up cause complete numbness, and that is CREEPY
