Did you wake up today and think "Today would be PERFECT if I could just find a giant penis and scrotum made of pennies?"
If so, you've found your nirvana.
This is definitely a fun off-strip destination and if you get the Groupon that is usually available, it's even cheaper. The museum is extremely sex-positive and showcases all sorts of aspects of sexuality. Souvenirs from The Chicken Ranch, Hiter's mistress' panties AND clear timelines of political and religious sex scandals... Check, check and check.
There's also a wall dedicated to victims of sexual trauma and it's a moving tribute to the strength, courage and fortitude to those people.
