Does the emission of one or two drops of manī (spermatic fluid) without pleasure or lust necessitate ghusl (ritual bathing)?

It is not among noble manners to play with one's private parts if it is not intended for arousing desire. However, if it is intended for arousing desire and obtaining pleasure, then it is forbidden, due to the Almighty's saying: "And those who guard their private parts Except from their wives or those their right hands possess, for indeed, they are not to be blamed But whoever seeks beyond that, then those are the transgressors." As for the emission of semen without pleasure, it does not necessitate ghusl (definition) (ritual bath) according to the majority of scholars, whereas the Shafi'is deem it necessary. If its emission is accompanied by pleasure, then ghusl is unanimously obligatory.
