NBE herbs do have the potential to lower or destroy your sex drive and your ability to perform. Do you still want titties even if you can never get it up? Are you in a relationship? How does your partner feel about you growing breasts? S/he has a right to know. How are you going to deal with family, friends and co-workers when the mounds on your chest are too large to hide? Breast tissue is somewhat solid and not easily disguised if you plan on still being perceived as a male. Smaller is easier to hide than bigger, and the process usually takes a few years so there is time to stop if you decide to, but there are a lot of things to consider.
