Wow, THREE hours??!! I envy your gf!
I'd be willing to bet that my husband has never gone for more than 20 minutes tops (most times it's 10 minutes or less), and we've been married for 24 years. I'd say you're lucky that you can last that long, but I'm not so sure that you're that happy about that. Maybe if the girl would use her hands or mouth on you, perhaps you'd get more excited and maybe not last as long? That is definitely an above 'average' amount of time, but I see nothing wrong with it; it shouldn't cause you harm in any way other than being frustrated that you're lasting that long. Maybe you just aren't with the right girl? Or has this happened with every girl who you've ever been with? I really wish my husband has your problem. Sorry, I don't mean to make light of it; it's just that I get jealous or something when I read some of these threads. It doesn't mean that your sitatuation is any less annoying than some things that I have to put up with here. I guess we all have our complaints, huh? Well, I wish you luck in climaxing sooner. I hope the girl is willing to work on you a little more or something. Unless I misunderstood, I'm assuming that you aren't intentionally holding back all that time, or I guess you wouldn't be posting with a problem then, huh? Take care.
