I was wondering if it were possible for a man to tell if a woman has had an orgasm. If so, how noticeable is it to a man and is there a substantial amount of fluid involved in a woman's orgasm?

I have a question. My friends often make jokes about something called "fisting." I feel really left out when they joke about it, so could you please tell me what fisting is?! Thanks a lot.

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?!

1) I know this may seem like a strange question, but what exactly IS pre-orgasmic? Does it mean that a person hasn't yet had an orgasm, or that her body isn't ready yet? I remember reading in one of your answers that many women under the age of twenty are pre-orgasmic. Why is this? Also, what is/are the purpose(s) (besides pleasure) of orgasm in women?

2) Hi, I'm not from the USA, so you may call me "the foreigner boy." I'm a 20-year-old male... I have had a lovely, nice, 19-year-old girlfriend for the past two years and I love her very much! We've started making love after six months of being together. We’ve had oral sex since the very beginning of the relationship. My girlfriend was a virgin before we met and me too. The problem is this: She never reaches orgasm! We really did try it all... it's very disturbing because she doesn't understand why I think it’s a BIG DEAL! And I really want her to have orgasms, but she just can't reach it... We really did try it ALL!

She tried to masturbate alone a few times and still had the same feeling... It’s not that she doesn't have fun, but she never really reaches the Peak! It seems as if she is stopping herself from having orgasm. Any secret I haven't read or heard about could be helpful! Thank you for your time!
