My boyfriend and me are having trouble putting condoms on his penis... We try rolling it on but i can only get it halfway down his shaft and no farther... Then the condom comes off in the first few strokes... His not circumcised so his got all the loose forskin still... And his penis is pretty fat in the middle

Should we try a bigger condom or a special make or is there a differant methods we can try??? Plz help cuz its really effecting our sex life!!!
