There are a bunch of sexy and exciting videos on Pornhub called ‘Cock Hero’ that are compilations of best scenes set to music and a changing beat you keep up with. Very stimulating and some are impossible to beat! They are made for a hand masturbation so you have to adjust the speed dial a lot. It’s fun! That may help with delayed cumming. Use the lube and refresh it with a water spray bottle spritz into your receiver and penis. Saves lube to a point and restores that slickery sensation!
