So, last year I had a one night stand with a guy in his twenties (I'm mid forties) who was then leaving to work abroad next day. Basically I needed to get back in the saddle after 5 years with no sex. It was a bit of a headfuck as I wasn't sure whether he'd enjoyed it or not and I obsessed about it for months. Anyway, he has unexpectedly come back to the country and pursued me to pick up where we left off, I put him off for a few weeks (didn't want complications of casual sex, worried about age gap and usual female insecurities blah blah) but contacted him last week and he came round at the weekend. He wasn't feeling too well, he's had a facial injury and he was tired but we started really well with foreplay leading to me giving him a condom to wear. He was very excited up to this point, but I know he doesn't like using condoms due to less sensation. Then as soon as he entered me, he lost his erection. We tried to get him going again but to no avail. He said he wasn't feeling well, I asked if it was me (he said no, I looked amazing -stockings and sexy undies). He left shortly after, saying we could meet up again, but I didn't say anything. Basically I was mortified and blamed myself. He text me when he got home saying he was feeling sick. We've not been in contact again other than me texting him to see if he was feeling better a day or so later (he said he was getting there).
Now I don't know how to play it, whether to contact him or not. We are both single, it's only physical, and my free time is limited as I'm a single mum, but I'm not sure whether to contact him or wait to see if he contacts me. I'm thinking I feel bad about what happened, he will probably feel worse and may not want to risk seeing me again in case it happens again. I feel a bit in limbo but don't want him to think I'm pressuring him if that makes sense?
Any advice chaps? And has this (loss of erection) ever happened to you? Was a first for me so I wasn't sure what to do.
