A slight tingle in your privates. Like the way when you smoke a bowl of weed you feel it first in your crotch and it radiates out. You realize the tingle is caused by the energies coming off that fine dark wood the room is walled in. You put your hands against the wood and tingle gets stronger. A energizing and erotic feeling. You can feel your public hairs crackle and writhe about like eye stalks searching for sex.
