As for tattoos, I tried temporary tattoos for silicone and tpe sex doll. It does not seem to be very well bonded and almost immediately becomes cracked and peeled off. Maybe there are some tricks I don't know, or I need a temporary tattoo with better quality. If you are an artist, you might draw a tattoo with a permanent mark and then occasionally touch it. I know you can pierce the silicone doll, but I haven't seen/heard of someone doing the TPE past regular earrings (I will do the same). I hope that you can because I want to give a sex doll a nose nail, if possible, the navel piercing. If someone has not done this before, I will not take risks.
