<human>: Provide a brief overview of the text.

First, let me start off by saying that lately I haven't thought of myself as very attractive lately, because my acne has gotten a lot worse in the past month or two. I don't know if this is twisting my interpretation of the situation, but I feel it's a useful piece of information to help you guys with advice for me.

The last 3 or 4 times I've tried to do anything sexually, she hasn't been into it and it's been like 2-3 weeks since we've done anything. Then last night, we finally have the place to ourselves, and I try to get things going and she stops me after our clothes are off and says that she just isn't feeling it. It seems like she hasn't been feeling it for a while now and I'm getting a little concerned. 

Also, she always turns the lights off when we're about to do something (this might be based on her own insecurities though), and she really wanted to get some alcohol for last night (which as someone who is under 21 is hard to get all of the time and last night didn't work out). 

So is the only way for her to be sexually attracted to me is if she can hardly see me and her judgement is impaired? And should I talk to her about it? I have some reservations about asking her because I feel like maybe it's all in my head and I don't want to be putting something out there that isn't really there. Thank you for your help.
<bot>: I feel that my SO is not sexually attracted to me and I'm worried about asking her because I believe it might all be in my head.
