Hey man, They look like bitcth tits, but if its real gyno then you will have a lump, a hard noticable lump under your nipple. Trust me I got it now, and it dose look alot like yours. Check with your doctor if you do, because any lump in your body SHOULD be removed, it can become a danger!
I have surgry sheculed for march, but it was hard to get my GP to hook me up with a surgeon, because of the roid use, so be prepared to be persistent.
If there is no lump, then you will have to just work on losing body fat, and perhaps use some Yomiburn(please note, that I have NO experience without the lump, so if you donot have a lump, resaerch and ask more questions. That way someone who has had a chest that looks like breasts can help you to overcome them and build a stonger lookin chest)
also my doctor told me lots of adolesence and teens develop gyno that eventually goes away, so if your young, then defeintly just talk to your doctor about it!
Cheers
