Well regardless what path one chooses there are several factors to consider.
First is extraction of the semen. I'm sure we can all image ways how this can be done. It might make a difference if one is using their own semen or somebody else's. The reason this is important is because if one knows how to raise and cycle their energy they could hone in on the semen and inaffect charge it or alter its qualities. This is a pretty important factor as it can affect the out come of one's magick.
So then how does one go about containing the semen? I think a condom might make an ideal catcher but I don't know if any spermicide on it might affect the semen. I suppose one could use their hand, even the mouth, or ejaculate directly on an amulet, doll or perhaps even a penticle.
Then the question is how to use the semen. This probably depends on how one contains it. If in the mouth then one would be mixing their energy with the semen because of their saliva. This could be an advantage in that it would personalize it for their magick. If vaginally the energy could absorbed directly into the body. If one ejaculates directly onto the item they wish charge it would instantly become charged. It is also possible to mix the semen into an elixor/potion of various other elements one chooses (including a collection of semen or other bodily fluids from several people) and use it as an oil or additive for a bath or food.
The final thing to consider is safety. Obviously if the semen comes from the same person who is using it, this is not a big concern. But it the semen is comming from others then one would want to make sure they use caution.
