Does exercising on an empty stomach maximize fat burning?

I have recently learned that in order to burn fat as a fuel, your body requires carbohydrate. Up until this point I had been doing cardio training first thing in the morning on an empty stomach, as I had read that this is optimum for fat burning. However, now I have a small carbohydrate snack before I train in order to prevent my body using lean muscle tissue as a fuel. Today I have again read in another book that training on an empty stomach first thing in the morning burns the most fat. I am a little confused over the best thing to do! I train with weights twice a week and do cardio three times per week. I do want to maintain my lean muscle, but am looking to reduce my body fat.


What's the difference between fluid during arousal and discharge?

This might sound like a gross question, but I do need an answer! When my partner performs oral sex on me, I'm not sure if my vagina is moist because I'm wet or because I have vaginal discharge... which is what? Isn't it normal for a woman's vagina to be somewhat moist, and to have a little discharge? When a woman gets wet, how can she tell? And know the difference between that and discharge?

Also, my partner and I haven't tried intercourse yet (I am a virgin)... I've read your previous answer to a man who said his penis might be too big for his partner; I am worried that I'm too small/tight for my partner. It doesn't look easy for him to even enter, and I don't know how I can make my opening wider to accommodate him (how much foreplay, how long?). How much pain does the woman feel? Thanks a lot!!


Why am I foaming after sex?

Today my partner and I were having sex and he "released" himself inside me. After sex, he began using a dildo on me until I was satisfied. Well, after going in and out of me real hard and fast, a foam-like substance began to appear. The foam was exactly like hair mousse. I am not on any type of birth control (he has a vasectomy), and I was recently tested for STDs a couple of months ago and everything was fine. Could you please tell me what this may have been from!


Why is my boyfriend modifying his penis?

My boyfriend went down to the Village last night and came back with a pierced cock and I am completely grossed out by this. Moreover, he wants to have sex with it on, but it is of the type that would definitely scratch my insides up. What should I do? Also, he's thinking about getting his cock sliced into two parts. Alice, he's freaking out on me. I'm scared for him.
