IMO virginity isn't really the physical part, but rather its a lot more mental, the attachment and longing.

If it's physical, you would have lost it to your hands, but that is not the case, thus I feel if one wants to lose virginity, do it full fledged with a FJ. Even if didn't eject, your body will feel a sense of longing to be close to the one u lost your virginity to.

As a tip, some bros can be too used to the death grip of a hand, and when comes to women for the first time, likely cannot cum or become soft, if that happens, don't feel too bad about it, sometimes the blue pill helps.
