I've also had sexual performance issues.
Everyone has, to some degree.
Here are some tips I've found to work wonders.
STOP WATCHING PORN.
Don't stop masturbating, just stop watching porn.
You are distracting yourself from your own body and your own source of pleasure.
Be more aware when you masturbate, and explore yourself.
Figure out what thoughts turn you on, etc.
This will put you more in tune with yourself.
Do PC exercises, Kegels and practice deep breathing.
Read "Multi Orgasmic Man" and "Taoist of Sexology"
They are like the bibles of sex. Seriously.
They will change you life.
Learn to communicate better with your partner.
Learn to laugh and relax when things don't go the way you'd like. (Or the way you've been programmed to expect)
This is invaluable!!!
Also, build a connection with someone you can trust.
After all, you will be swapping energies with the person you have sex with (read the books!!!)
As far as sex on acid goes...
I would advise against it for several reasons:
If you are feeling self-conscious/impotent/sexually inadequate, those feelings will almost certainly be magnified by an immense degree under the influence of a psychedelic.
That can be very beneficial and healing if you're alone, you can learn from it.
If you're with someone however, this may lead to a horrible experience.
Sort out your mind/body connection while sober first. Get a stable grounding.
Then maybe try a small dose of LSD and explore YOURSELF.
Then try and explore with your lover while sober.
Be slow and break any cycles you might have had previously.
Relax and just have fun! Don't expect anything to happen.
Communicate and trust!!!
Then when you feel more confident and stable, you may try a small dose of LSD and sex in a relaxed environment.
Sex should be fun, funny, love-filled, and happy. If it's anything other than those things for you, it's time you've torn down your previous expectations/methods and started from square one. Be a kid again, masturbate for the first time!!!
Also, don't even take any supplements unless your doctor recommends it.
Natural test. booster/vasodilator :
10-30 min light jog/cardio, eat a beet. (They say BEET-RED for a reason! Your veins will be surging!!!)
You can also take Fish-Oil daily to help with blood flow.
Cacao will boost sexual desire and performance but don't use it regularly.
Best wishes!
Heaven existing here between Hell
We surf the transient wave, balancing on our breath, building and destroying until death.
We are the divine creators and destroyers.
We are the portals & black holes.
We choose what we manifest at the present moment in whatever dimension we inhabit.
