I've often heard that guys with super large penises (like 8, 9, 10" or more) often cannot achieve firm, hard, full erections. Is this true? I'd like to hear from some of you horse-hung guys (either gay or straight) out there. Do you get fully hard and erect, or does it kind of "hang loose" and stay a little limp? Does it stand at full attention, or is it still partially at ease? I'd like to know. Thanks!
