Normally I would consider it spoiling and going rotten to be what makes it dangerous, but Pippa has a natural resistance to rot and mold considering her daily life.
Furthermore, provided you yourself do not have any parasites or STDs, your cum should in theory be pretty sterile.
Therefore, so long as you send it in a properly hermetically sealed jar that you washed and sterilized beforehand, there should be no problem.
