I have imaginery girlfriends some are japanease the others are from manga ans anime and im afraid to ask real girls out because i dont like being rejected or cheated on what should i do?

Every boy has had to deal with rejection from girls. That is a normal part of growing up. Quite frankly the cartoon "girls" you fantasize about will never be as much satidsfying, as much interesting, or as much fun as having a real relationship with a real girl.

So suck it up and go get rejected a few times, its no big thing really.

If you hear 100 say no and one says yes, then you win!
