I wouldn't listen to the gay comments, nor would i pay particularly attention to any ED comments.
A few years ago I remember having the same problem you comment on, initially it was keeping hard (after foreplay), then it was ejaculating... i read loads of information on the internet and almost convinced myself i had a problem with ED ; no morning glories, losing erection easily etc etc. I almost went to see the doctor.
Basically long story short it was self induced pressure; experienced new GF, and i had convinced myself I needed to be 'the man'. Our first night together hadn't gone to plan, and so pressure mounted, anyway 3rd/4th time lucky ( a few drinks) my member stood to attention, ejaculation took a while( which i'm sure was a good thing) but eventually I came. i've had absolutely no problems since, with her or any other GF's. TBF I explained the situation to her, after all it was her fault ;-), and she was very understanding and didn't put any pressure on.....
Good luck
ps. morning wood has returned.
