Prostate orgasms and poor mental health - possible?

I believe the journey is 75% mental. You have to be able to meditate and let yourself go. Especially as sessions cam take up to 60-90 minutes to hit crazy highs. Very few people in today's world can actually switch off and meditate / block all other thoughts out for that long. 

Look at how often people are on phones etc. Everyone constantly connected and chasing dopamine.

I would look at starting to meditate daily and maybe have a session once a week or once every 2 weeks. But be sure to meditate every day. I personally use some sort of music or binaural to meditate. These greatly helped my sessions and also mental health.

At the start I would have sessions where after 20 minutes I get bored and want to look at my phone. Later down the track I have had sessions where I am literally floating thru space in pleasure for 90 minutes with not a thought of the real world. 

As for mental health. If you are not exercising. Start it. Start slow. That + meditation will drastically improve. Also eating better. Combine those 3 and your life will change. 

Of course poor mental health could have a detrimental effect on the results of anything you’re undertaking. Mindset,confidence and belief are just about everything on the journey. Once you believe in your process and yourself,it’ll come easy as the confidence is there,so relaxing into it is much easier,and one moves on from hoping things happen to knowing things will happen. 
There are other factor at play such as maybe suffering with siege mentality. Session frequency,session length,ability to get sufficiently aroused etc. Ultimately,you could do everything else right,which a lot do,but can’t get the head in the game,so it all falls apart.
