I'm 19 and my boyfriends 21 we've been together a few months but recently I feel like he completely avoids having sex with me, we haven't had sex for a month. He's had many partners so it confuses me that he wouldn't want to have sex with me, he always tells me how pretty I am and how I'm his completely type, everything about me. When we do have sex it's so good and he even says so, I just don't understand and it's making me feel so ugly and unattractive. I'm not a forward person at all so there's no way I'll be able to ask him out right
