Yes indeed there can be great differences in amount, viscosity, force of output and rate of output. But I do what I can and like it, although I much prefer when Red, who is a high volume, high pressure, high flow guy, ejaculates in my vagina. Hubby OTOH just slowly oozes a couple of dollops, which is much better for taking a swallow between squirts. Sort of like chocolate sauce coming out of a pump bottle.
