You need to read the rest of my post. There are many reasons why you have an itch.
well i haven't had any sex , as for oral sex its been months. i have not been in anyone else sheets. as of late that itch has not been as noticable maybe it was that i did trim down a bit after all the itching. don't know if that was it???
Have you had sex with anyone recently? Have you slept in someone else's bed without them putting fresh sheets on? It could well be pubic lice. They are more active at night. You an get some topical medication at the pharmacist. Don't be embarrased if you do have 'crabs' It is more common than you think.
It may also be an itch due to changing soap, or shower gels. Many people notice the itch at night. Try changing that first and in a few days if you still have the itch it is more likely crabs.
