For me one of the hardest things for me was the lack of orgasms due to pain and not wanting to have sex and i would want it but knew it would only leave me in pain. This hurt me mentally . My gf and I have found a good solution for the time being.
I bought this thing called "Manta" by fun factory which is a penis vibrator shaped like a mantaray so it doesnt fully close and can fit any size so it allows me to have a gentler experience and i can just keep it on the glans. Because it is gentler I can tolerate longer sex and I think it may be having an overall positive impact for blood flow. Too soon to say about that, but mentally im in a better place because I can be partially satisfied now at least lol. GF is happier with it too for obvious reasons i was shy to show her at first just because i always thought a vibrator was a "girls" thing. I wish I would have known about it sooner i think it is probably the safest way to get off and leaves me in the least pain.
one thing i do worry about is vibrations creating microtears if i use it on high settings, but i think even then it shouldn't be a problem. I wouldnt use a high setting right over the plaque
