Aaq, you don’t need rabbi yoshe ber soloveitchik to pasken that; intentional exposure is clearly outlined in shulchan aruch and poskim.
Rav belsky told me that a frum person studying psychology is allowed to do so and “not be gores” garbage that is part of the course – now i don’t know if this psak applies only to someone who sat and learned for years in yeshiva, and for instance, would not apply to a woman or younger bochur who was not matzliach in learning.
