Still seems dodgy. 3hrs per day on Facebook and Netflix and Youtube corresponds to very few search engine searches. Very few people are spending a comparable fraction of time on porn; it's a self rate-limiting activity. Beyond leisure time, a huge portion of people use Internet for work some or all day. Millions of people stream music all day. Porn is the least optimized search target so you'd expect more porn searches per session than other topics searches per session. 4+% of "things people do" in some sense? Sure.
