I have experienced threesomes, both from sharing and watching (and helping) a girlfriend with another guy, and from joining others....It is amazingly intense and erotic with the right people and chemistry - I find it as my most popular, rewarding, recurring topic or yearning or experience to explore online with literate, honest, and equally yearning chatters. I'm not into the stereotypical imagery or roles many associate with it (costumes, name calling, belitting, etc.), but I love seeing, helping, watching a woman really break out of her shell and be pleasured, shared, opened by another man and me...and whatever else happens with it.
