i've done this even with straight guys and once they get over the awkwardness it is very hot. you just relax into it and grip them together so the underside of the helmets rub together. also hot to go tip to tip so the penises are lined up 'eye to eye'
thought of having actual sex with a woman IRL sounds exhausting, wonder if i'd be able to even get an erection it's been so long since i've been with a broad. but laying back with another man and rubbing our lubbed up cocks sounds like heaven on earth. so hard thinking about it. just sucking and rubbing cocks together is like the ultimate sex, can imagine doing it for days whereas with a woman after 20 minutes im not sure what to do with her
