Exuablv has created a wonderful set for mermaids, but I was not very happy that the mermaid's penis comes with the tail.  I changed this penis and made it a separate body part for mermaids(The "CAS_exuablv_merman_penis_hard_ANIMATED" file which Adds the penis as a Glove) It is now in the Gloves section!(I did not find another solution, if you have any ideas please write.) In connection with this, so that the penis does not disappear during sex, you need to make in the WW settings
