Guys. How do you fill a cup without spilling?

[Anonymous]

I need to fill a sample-cup with sperm for laboratory testing. But with my dick pointing straight up, it becomes pretty difficult to fill a cup without spilling. Keeping the cup against my dick when coming, will mean it runs straight out. Holding the cup upright and aiming, means half of shoots way over it. Any guys (who have a pointing-up-penis) ever had to fill a cup. And how did you manage?

Is laying on your side an option? That way you can more easily direct the semen into the cup without much (if any) spillage.

Finish on the toilet so you can have support to put the cup lower and avoid bending your junk.

Put the head as tight as you can at the mouth of the cup and aim for the side.

Cum into a clean plastic bag then transfer it into the cup.

Plastic bag are not sterile, and the chloride that is used in it to make the plastic bag soft might kill the sperm-cells, thus giving wrong information.

Have the hot nurse spit it in the cup?

[Sirisaac]

Why are you doing this? And I would say to cum into your hand, then just pour it into the cup.

If it's for lab testing, it could contaminate the sample.
