A tumblr page I follow actually shared a link on this today. Thanks for asking on such a convenient day. :p

"The 130 men selected for the Teleiophilic Profile group responded substantially to prepubescent girls but even more to adult women; the 272 men selected for the Pedophilic Profile group responded weakly to prepubescent girls but even less to adult women. In terms of absolute magnitude, every patient in the Pedophilic Profile group had a lesser penile response to prepubescent girls than every patient in the Teleiophilic Profile group"

Also Newgon has data from various sources as well (https://www.newgon.com/wiki/Research:_Prevalence)

Some show the majority of normal men are attracted to children and some do not.
