I've just turned 18 years old and got kinda sick and I have to take intramuscular antibiotics to treat the disease.My father does the injections because he is a nurse so he knows what to do.But I feel so damn emabaressed every time he does it because I have to stay on my tummy while he does the injection in my bum,with my panties off.It's also really painful. It kinda feels weird because some time ago he was drunk and when he came home thought I was mom,it was dark in the room and grabbed my ass. And this is not the first incident that happened.I felt like dying of shame when he stepped into my room while I was bare naked changing my clothes or while showering he entered the room not knowing I was there or at least that's what he said.It's just makes me scream with anger. I'm not that close to him I just don't feel comfortable next to him,even when he hugs me or kisses me I feel kinda disgusted and now I have to bare this standing with my butt naked in tront of him while he does my injections.
