Hi Nurse. Couple of things: don't get pregnant with him. Address this NOW, because the more you stick around, the harder it will be to leave---as you acquire material goods, such as houses, cars, etc., it just makes it seems like you have more reasons to stay together. Herbal or homeopathic remedies are crap. The only thing that might work for him is a scrip for testosterone, and you know that the only way you can get that for him is if a doctor checks him out, which you say is not likely.
He sounds like a real gem. Farting during sex is just plain rude. Tickling is weird too, because you must have told him that you hate it. And 3-5 minutes after instant penetration? Tell me again why you married this dud?
Finally...one more word of free advice: Stay married for a full year or you're obligated to return the wedding presents!
Hairdog - who is a real gem, and twice as precious.
