More About Snowballing
Snowballing is a practice synonymous in both heterosexual and homosexual sex. Snowballing can involve two people or more, and can involve more than one person’s semen being passed from mouth to mouth. When there is more than one partner involved, the quantity of semen increases as it is passed, hence the term snowballing.
