So I managed to take a girl back to hers the other night, and made it to her bedroom, quite drunk. We started making out in bed and proceeded to sex, however I could not get myself erect. I tried to do the gentlemanly thing and make her orgasm, but she/I kept losing momentum and gave up in the end. She tried mounting me, but again, no go.
It was my first time, or not as the case may be, so I'm putting it down to nerves and being considerably drunk. We fell asleep before either of us were finished and I left awkwardly at about 4pm.
My question is, as I'd like to see her again, should I text back explaining what happened and if so, how can I do it in a way that doesn't undermine my masculinity. I'd rather not leaving her thinking I was just drunk or whatever else she might think I thought of her.
Thanks in advance.
