Aless, relaxation, need advice.

Hmmm, you might have to change your relation with those feelings. Firstly, you should not be panicking if you are laying down in your bed and you get sudden sexual arousal. That's the safest setting for this to happen, and also the best place to learn how to deal with it. Maybe go to bed an hour early and try some experiments ? You'll have to figure out what triggers Aless for you and how you can work around it. 

The main issue when such a question is asked is that almost everyone else is trying to make these feelings grow, not suppress them... so few people have experience in avoiding Aless manifestations.

@zentai solid advice, it is better to look into the eyes of fear. Instead of suppressing

There's a lot at play here. You can't be stressed out all the time because some prostate feelings might manifest themselves.  This is absolutely something you will have to deal with, yet it's still difficult to find info on this particular subject.

If you are a generally stressed out person like you said, then I would start by looking at the possibility that you have a tense pelvic floor, and I would consider this more likely if you spend a lot of time sitting down and if you don't exercise a lot. Then when you lay down and allow your muscles to relax, it would make sense that involuntaries would start from spasming etc. 

Obviously I'm not a doctor and this is not medical advice, but I don't think you need to involve a doctor anyway. This would be more like back pain form bad posture or something similar. Looking at pelvic floor health in general and seeing if there are things you can do to improve this would seems like it's worth exploring. 

@zentai yes, I think it was hundred percent anxiety issue and has nothing to do with Aneros. Sure prostate is might be active for a while after long session. But my sensations I described have nothing to do with it. Once I let them go, they no longer bother me and I don't even notice them anymore.
