I have found, just because a male, black or white, is well hung doesn't make him a bull. So many men contact us stating they are bulls seeking some white pussy. For me, a bull obviously has a big cock, but he needs to be a genuine alpha male ( I can smell a true one from miles away) , manly, charming, confident and with a particular cheeky smile and swagger.
I think younger well hung men just assume 'bull status' because of their cocks, but for me that just doesn't cut it. They may be a stud, yes, and be able to fuck me in to the next day, but a bull has gained experience over time and has penetrated a lot of women before me, so when we get young ones contacting us, we tend to look but not usually get back to them.
I don't think you need tips if you are a true confident bull, you maybe a stud, a stag, but a bull I don't believe needs tips... not to say you won't become or aren't one, but a true one just attracts or senses where the available pussy is.
This isn't meant to be critical, just how we see and approach it.
