nikka im black. I guess god forgot about me.
That's the unfortunate part of "positive" stereotypes; it places undue pressure on people to be a certain way, over something that's probably not valid in the first place. You can't let this stick in your head, insecurity can feed into a vicious cycle of other problems that affect your performance in bed; issues that don't necessarily stem from you lack of size, and wouldn't exist otherwise.
Lose weight and exercise first off, you might find that increased blood circulation from becoming healthier gives you a bigger erection. Same with being confident. Having confidence can literally increase the size of your junk:
Confidence Can Actually Increase Size of Man’s Penis, Doc Says
( that just doesn't apply here, being confident can help you compensate for what you lack in many other areas too)
With that out the way, you got to apply some perspective too. Women will look past a lot if they genuinely like you,including your size, and sex isn't that high of a priority to a lot of women too when it comes to finding a quality mate(A bit of an anecdote, but it seems like a lot of women have shyt sex and learn not to care so much about it later in life ). And regardless of what a lot of what people tell you, intimacy and the feeling of being close to someone is the ultimate enhancer for sex, with technique following behind it, not penis size. Don't let this shyt stop you from going out there and playing the field; there isn't much you can do with what you got, but letting insecurity hold you back from living life to it's fullest is a way worse feeling.
