Well even though friends often do have a lot to do with relationships, I feel that the relationship isn't between you, him, and your friends; it is between you
. Ultimately it is your decision to date or not, there isn't (or shouldn't!!) be anyone forcing you to date anyone for any reason. If you feel that you aren't ready for a relationship, then it is your decision to make. Nobody should force you to date or not to date.
About him seeing the "real" you though.....
Personally, I think that any decent boy should accept you for who you are no matter what. If you start dating him and he sees the "real" you and then decides to leave you because of that, well I think that says that he isn't ready to accept you for exactly who you are. If you do start a relationship with him and he can't handle being with the "real" you then I think that is his problem not yours. Any guy that really would/does love you would/will stick by you no matter what
. If he doesn't have the decency to stand by, support, and love the "real" you then I think it might be better off that he leaves because you deserve someone that will be there for you 100% and more.
Hope it helped at least a little bit
and if you've got anything else you want to talk about don't be afraid to message me if you want.
