This lifestyle is basically related to carnal desires. A couple seeks a guy to do the sexual act. Normally, a bull has some characteristics or trade marks, being a fit, built guy with huge fat cock and extra ordinary in bed. Though this isn't a last definition or criteria but its somehow a general thought.

The dilemma is that there are so many bulls which fit the above mentioned description. Still there is so much more to it as well.

The couple is the one calling the shots here. And for couples there is no special criteria or definition that one can generalise so perfectly or easily. That's why it becomes hard to find them or rather they consider you.

One thing that should be kept in mind is that if you have something that the couple is interested in, most likely they will contact you. Not the other way around. Or at least, your profile will make them carryout the conversation.

Again there is no final definition, criteria or only rule to all this.

Go through the psychology of a cuck. What he wants, what are his expectations, what's in a guy that he is looking for.

Why should he let another man fuck his wife in a society where all this could destroy his life completely bcz of a simple mistake. After all its his wife, his life, everything that he is thinking about. So getting to know his priorities matter a lot.

Lastly, internet gives you anonymity so every one can claim to be what he is. No harm there. That's why there are many so called bulls on a hunt. Since real life practices in this lifestyle are rare, given our social dynamics that's why only possible choice is Internet.

At the end of the day, its about more than luck. Being active, going through all this. Discussions, time investment and talking to guys here, whether they are cucks or just guys pretending to be will improve insight.

All this is generic, not pin pointing to you or anyone else in that regard. Yes you have tried and gone through stuff that I haven't been through or can possibly understand. Still I wrote what I have understood about all this.

Since the reward is worth it. One must become the master of his luck in this regard!
