In short the answer is yes, Emisil Erect packers can be used for FTM penetration. However, as with all the other sex toys we do recommend you to be cautious and aware of the health risks. We suggest you to wash your FTM pack and play packer before and after sex to avoid risks associated with sexually transmitted diseases. Additionally, Pack and Play FTM packers are made from medical silicone which is totally safe but it was not intended for sexual penetration. If you choose to have sex with FTM Erect packer - the use of condom is required. Also remember to use water-based lubricant only as silicone lube can damage your packer in the long term.
