I Love Anal But Wont Cum From It

I discovered anal very young, I had a few gay experiences before being able to ejaculate, and as soon as I left parents’ house I brought toys, I have always had at least one or two handy, every gf I had was into dildoing me, and my wife is alao…

I LOVE masturbating while I’m filling my ass with a thick something: dildo, vibrator, cucumber, a dick, anything is good…

The thing is I can’t cum from anal stimulation like you see in porn, I love it but my dick gets usually hard for a few minutes and then flacid, it wont stay up even when Im literally moaning in pleasure, I usually go for a while with anal, the when I’m ready to cum I need to stop anal, and either masturbate or fuck my wife (same with exes) for me to come, it suits the need but sometimes I would just love to come without the need to stop the anal part… there is one way my wife can make me cum that involves anal, she put a dildo on me and rides me, feels good getting pressure with her pushing the dildo a little with her weight into me, but still doesn’t fit a proper freehand cum, I just can reach it
