This ... the sexual energy is the offering. Not the semen itself. Although, some succubae do like that sort of thing, no doubt.Coervus wrote:I'd recommend doing the deed as the offering in the presence of the vessel or altar, not offering the resulting... material.
From-the-source and after-the-fact make a pretty big difference in what this particular offering represents.
In this case it is the act more than the result that is of particular value.
I also recommend taking your time in carrying out the offering. Tell her you want to offer her your sexual energy, ask her to be present during the "ritual", and just take extreme time getting to the end result. The more energy you build up the better.
