hey I'm 16 and shaved my pubic hair for the first time first I trimmed with sum scissors then used gillete shavin gel with a new wilkinson sword quatro titanium it was fine for about a day and was really smooth but then I got these red bumps and it started itching is there anything I can do I want to keep it shaved but don't want the itchness or ugly looks down there any help appreciated thanks

Wait about three days and do it again... as your skin becomes accustomed to the razor they will subside. Also wash well with soap and water BEFORE shaving. You'll have a little stubble on day 2 and 3 but I find every 2-3 days and its won't itch.
