Once while around 16 or 17 I slept over a friends house and we slept in the same bed and he had a bit much to drink and I had the desire just to feel what it felt like having another cock in my hand so I extremely carefully(afraid of him waking up and catching me) maneuvered my hand into his pants and boxers but was actually quite dissapointed how small(mainly how skinny) it felt compared to what I was used to(my own). If he would have had a big cock I would have probably been quite a bit more excited but eh.
