Does having a bigger penis mean more pleasure sense more nerve endings?

No: The glans penis is richly blessed with nerves and large one does not have more nerves. Please note that the biggest sex organ is the brain, not a penis!

Not necessarily!: For sexual pleasure, it is the art that matters rather than the size of your organ. Finding pleasure points for effective foreplay is always a good harbinger for good sexual experience. You should instead focus on your partners body in helping achieve a wholesome encounter that is mutually pleasurable. Good luck.

No: There is no evidence that penile size is connected to level of pleasure from intercourse

Nope.: At least not for you. It does not matter how big you are or are not, pleasure is the same for you. Now, the partners pleasure is something else. And it's possible to be too big or too small for someone else's preferences, but hopefully your relationship is based on something more meaningful than size of one body part. If that's the only thing that someone values you for, move on.

NO: There is no way to make a penis bigger. Don't believe the ads trying to sell you something that will supposedly increase your sexual satisfaction. There is a reason that spam filters send those emails to the trash. If you having difficulty achieving normal sexual function, talk to your doctor. Most of the time in someone young this is due to psychological factors that can improve with counseling.
