I recently met a man in person whom I initially started talking to on an app. He is in his 30s and seemingly fit and healthy. To put it bluntly, we didn't have intercourse because he couldn't get a hard enough erection to facilitate it. The best way I could describe it would be that it was semi-hard (or semi-flaccid, depending on one's outlook). It didn't get any harder. I didn't make a fuss about it, but the guy was clearly flustered and embarrassed. I was trying my best to turn him on and get him fully hard, but it just wasn't happening. He did use his hands and tongue on me, rather effectively I must say, but I really wanted to have sex. I haven't previously had an experience where the man couldn't perform, though I also haven't had a huge amount of partners. Should I just move on? Tell him to use Viagra if I see him again?
