issues or not?

Right so I am gay and attracted to men thatbisn'y a problem.
But the problem is I dont always get an erection the guy I'm making out with or going to take it further.
But there is this one guy, and well we just spontaneously have sex and I can easily get a full erection there and also when I'm either masturbating alone or watching porn.
For me this is a issue because I'm no longer having sex with this guy and I'm worried from past experiences that I will be unable to get an erection when I am actually with another man?
What would you advise?
Stop masturbating completely or anything else?
Thanks love to hear this help before valentines day

Hello,
If you were having regular erections earlier, what you are facing now is sex related anxiety. This usually happens in initial stages and the problem will disappear over a time. This seems to be absolutely natural. If your morning erections are good then the cause is psychological. Mean while you should take protein diet, regular exercise, remain stress free, and remove sex related anxiety. Also do not indulge in excessive masturbation.

I hope it helps. Take care and regards.
