So, I'm a 27 year old male that has only recently started having sex. I lost my virginity at 22, and didn't really have any sex again until recently. I've now hooked up 4 times, and I've had erection problems with all of the times.

It's not that I can't get hard at all. I got a spontaneous handjob a few weeks ago after a great date with a girl I met off Tinder. No problem getting an erection there. Then we went out for drinks the week after, and we end up at my place afterwards. We kiss and I go down on her a bit. Then she wants to fuck, but can tell I'm not hard, so she gives me a BJ for a while. We then try to have sex, but we end up stopping after a while because I just can't get fully hard. Cue embarrasement and her saying "It's OK. Are you nervous?".

When I try to think back, I don't really feel like I'm super nervous. But I think I must be, otherwise what would the problem be? Again, I'm 27 and in fairly good health, so I don't think it's that.

Has anyone tried anything similar? How do I cope if it's nervousness?
