Ed got me confused, pleaseee help

[Tellmehow]

Hi everyone, first please excuse my English! I’m experiencing very confusing situation! I have had many sexual experiences namely oral, handjob and intercrural sex (not intercourse) in which I never recognized any softness! I have been also masturbating fully hard almost everyday to porn for many years. I have tried intercourses (my first intercourses) 5 times with different women during the past 3 years and in all occasions as soon as I wanted to penetrate I went soft. One urologist prescribed me with Viagra and 25mg helped. Then I reduced it to 12.5 mg and it was fine! Yesterday I even cut the 12.5 mg to half and I was fully hard in missionary position for 4 times during 4 hours ! But I lost my erection in cowgirl position! The confusing point is that While I’m alone I get durable and strong erections lying down (including long and hard morning wood) but while kneeling I need more manual stimulation to keep it up but yesterday in sex it was contrary wise! Now I’m a PhD student in a European country and I don’t have a good insurance to do tests like doppler ultrasound. I’m really afraid of venous leak! Could it be performance anxiety or conditioning myself to masturbating to porn? I’m generally anxious and I have been taking paxil for panic attacks. Could you please help me with your ideas?

It sounds like performance anxiety, but What do I know?
Have you ever experienced it after having some alcoholic drinks?
Maybe that would remove inhibitions if that was the problem.
