My girlfriend and I have oral sex. I heard that if you blow in the vagina of a female that it could kill her. Is that true?

1) I'm 20 years old. I have spina bifida and I can walk perfectly normal but I have incontinence with my bladder. I get a lot of urinary tract infections, too. I've been with my boyfriend for 3 years now. I am kind of worried about having sex with him because I always pee myself. I was wondering what I should do to stop getting these infections so I get be comfortable during sex and not have to think that I will pee on the bed.

2) I have been friends with a guy who has spina bifida for a while now, and recently, things took a turn for the better — we are just starting a relationship. I know that he has sensation below his waist, and can get an erection, but I wondered if there is anything about how his disability will affect our sex life. I am anxious for it to be pleasing for both of us, and although we are open enough for me to ask him questions, I would like to go in prepared so to speak! Is there anything that will be able to help me in making sure that the first time for us won't be awkward, uncomfortable or downright crap?!

Sometimes I masturbate before I go to sleep at night. Usually nothing is wrong, but sometimes (and this always occurs at night, I've found) after I masturbate, a few minutes later I have to urinate. And when I do, it is usually very painful. The feeling doesn't pass either. My scrotum usually gets very tightened up, and there is painful feeling above my crotch. Usually I just sit there, drink some water until the feeling goes away. ANY idea what this is?

1) i have been experiencing pain in my clitoris and generally in this area. It's a sharp pain that happens with the lightest touch, crossing my legs, or from wearing tight pants. I've never had this before and i'm wondering what it is. Also i've noticed the hood of the clitoris when pulled back, you can see like an inner layer of skin. Please i'm very worried, can you tell me what these may be? thanx

2) Is there anything that can be done for clitoral pain? I have a painful clitoris that swells, itches, and hurts throughout the month. I have had pain with this for years now and no doctor can find anything wrong with it. The only physical evidence is tiny white specks of discharge way back under the "hood." But if I pull back to look to see if there is anything wrong, it hurts immensely for days afterward. It interferes with my sex life with my husband because of the fear of pain if he touches the area. PLEASE let me know if there is a condition that this is related to or if there is any kind of cream that can minimize the pain. I have tried several kinds of Vagisil type treatments, but they do not help. Thank you.
