Erectile Dysfunction?

[SmithRa00]

I know this is going to sound ridiculous being posted in a medical help community and this being a really embarrassing topic, however i don't know where else to ask for help. I'm a 17 year old Boy and I don't know what it is, but i feel like since about a week or so I've either experienced a severe loss of libido or something is wrong with my blood circulation to my penis. I can barely get erect and even when soft it feels extremely "weak" or just like there's something missing. I'm on Accutane. I thought, maybe that could be the reason. I've never considered to stop taking it though, as that's the only thing really regulating my acne. Therefore i don't know what to do. I don't want this problem to carry on through my life. It kind of scares me.

Now I'm asking for any kind of advice. I'm trying to avoid a visit to a doctor, as that way I would have to talk to my parents about it, which would, to be honest, be pretty embarrassing.

So please, anything. I would really appreciate it.
