Have met both women and couples via this site.
Couples haven't turned out a hit, there's usually jealousy involved from the guy in the couple. Sometimes the woman had more or less ignored her guy during play since I and my doggie were the new and exciting thing. Even without looking straight at him I could feel his resentment. Wonder what the car ride back was like for them?
Women, when they've made up their mind, have been less of a problem. My problem with THEM on the other hand has been that they many times have been extremely dishonest. About their looks and weight. One woman described herself as tall, slender and mediterranian looking. She was short, fat and very pale.
There were no problems though with "I don't want to do THAT", whatever THAT was. I'm mainly talking sucking and anal. One practical problem was that the doggie sometimes, in his excitement, slipped into her asshole, without lubricant, which was painful. One solution to that problem was her inserting a buttplug before playing.
The most occuring complaint from women I've met was that other men they had contact with chickened out at the last minute. Mostly because they in reality had no dog to offer.
If you're a guy reading this think of the mafia phrase "can he deliver?". It was about delivering alcohol during the prohibition. Chicks think of us men in the same way. Make sure you can deliver.
Advice to other guys:
While communicating with her, avoid talking about all the sex stuff you want to do to her. Why you ask? Well, when you meet her, maybe you won't feel inclined to do to the REAL her what you imagined you wanted to do to the IMAGINARY her, who is always hotter and better.
It turns you on to rim a woman? What if it turns out the REAL her's asshole isn't that appealing? Either you have to be a man of your word and do something unappealing, or, you turn out to be a bullshitter, who just talks. Because the promise of getting rimmed was what finally made up her mind. And you disappointed her by not wanting to do that.
Make no promises you can't keep. Like having a dog or not. Your neighbor's dog, your grandmother's dog, living far away from you, a stray you saw on the street - nothing of that counts.
Meet in a neutral place. A park, a restaurant, a beach. Make sure to bring the dog. Don't ask her whether she wants to go on with the whole thing or not. Separate from and digest the meeting and then text or call each other after having decided without pressure.
A peculiarity with women is that they will without further ado DO some sexual stuff, like for instance collecting sperm from her pussy in a glass and drinking it, but they will dislike YOU talking about it.
Women like to be treated with normal civility.
She may just 10 min before, have taken dog dick and your dick as well in all holes, but now that it's over, she wants to be a lady. Eat that after sex meal with her like a gentleman.
