If you're experiencing light bleeding then you shouldn't be using tampons at all because this increases your risks of TSS. I'm not sure what you mean by causing bumps, tampons go inside your body and unless you regularly examine yourself wiht a speculum you'd not be able to see any bumps inside your vagina that could be caused by tampon use.
If you have bumps around your vaginal area going to a doctor would be the best things to do. It could be one of a few things, non of which would be pleasant.

A growth in the vagina is not a normal occurrence. It could be that you are feeling your cervix or urethral sponge, which are both pronounced in the vagina. If the growth is a new problem, or you are unsure that it is a normal part of your vagina, please see your doctor/gynecologist for an exam and proper diagnosis.
No, blood will not kill any sperm inside a woman's vagina. At most, the flow will flush out the remaining sperm over time, but do not plan on it. However, if you had unprotected sex you could get pregnant.
Shave the hair in one direction. Do not shave against the direction of hair growth. When you get bump use a solution such a bump stopper to dry up the bumps. Be very careful so that the solution don't get into your vagina. That will be very unpleasant. If you cannot get bump stopper solution use rubbing alcohol. remove the ingrowing hair from the bump with a pin. Again be careful you do not want to cause damage to your vagina. This routine will have to be repeated as long as you continue shaving as there is no known cure for hair bumps especially on the vagina. Good luck
