I came to watch bb porn because I like only bb sex. For some it may introduce them to bb sex, but for me I found bb porn long after I was into bb sex. What it has done is open me up to more types of guys. I have sex with guys I would not have been interested in several years ago because I have seen how hot they are in porn. I have also broadened the type of sex I'm into. For me bb porn has been positive. It is rare for me to watch condomed porn. The guy(s) really need to be hot. Most of the time they will eventually do bb porn anyway. I don't think bb porn leads you to bb sex, it just gives you permission. Eventually you would do it anyway. Those guys who are really into safe sex are not going to go bb just by watching porn.
