My SO and I had sex last night it's been about a week since we've had sex well it was the usual touching then I went down on him it was within 30 seconds he got off and that never happens usually I give him head for several minutes then we have sex... I'm just wondering why this happened. This has never happened. Did I do something wrong? Is something else going on I need to know? I need help I don't want to overthink this.
