My new partner is a little on the small side . We had sex for the first time last night and it didn’t go as planned ! There was lots of foreplay a bit of sex but he was losing his erection ! He didn’t mind we just continued minus the sex. Now I’m feeling really embarrassed about this thinking maybe I wasn’t good enough? I have had 3 children but my I’m toned down there I was checked over by a gynaecologist. What is going on ? Everything else is so good
