Here’s how the scientists explain it:
“Novelty itself contributes to pleasure, so seeking a more novel-sized penis may be consistent with a goal to pursue pleasure primarily in one-time partners,” they write.
“Women may prefer a smaller penis size in a long-term partner compared to a one-time partner for reasons of both physical comfort and a preference for less masculinity in a longer term partner.”
They expect women like a larger member in a one-nighter because it makes up for the lack of an emotional bond.
