The science of sex tries to answer the age-old question: Does size really matter? Delfine takes to the streets and asks women their preference on a range of dildos, but do the figures match up with real-life experience?
Delfine and her willing participant, Tula, have a wide range of sex toys at their disposal, from long and thick to short and curved. They offer different sensations and pleasures, but which one does Tula prefer? They talk candidly about their experience and sensitivities, and what they prefer when it comes to penetrative sex.
Delfine expertly uses the lubed-up toys on a blindfolded Tula, but will the one that makes her cum be the one she thought she’d like?
