Does sweating release toxins?

After practicing yoga in normal temperatures for years, I recently attended a heated yoga class (heated quite hot: 95 to 100 degrees!). The experience left me dizzy, nauseous, and completely enervated. Afterwards, I expressed my concern to the teacher, asking why the studio needed to be so hot. She "explained" that by sweating, supposedly the body releases "toxins" and that my nausea and dizziness must indicate that I need to "detox." Personally, I think I was suffering from heat exhaustion. I've heard this silly explanation more than once, as many people seem to believe toxins are released through sweat. But is that true??? And — next question — doesn't exerting oneself in extremely hot temperatures seem like a recipe for dehydration? Are their any benefits that make it worthwhile, or is all this heated yoga just nonsense?


How can I have more pleasurable sex when my partner's penis is too large?

I have encountered a problem I never expected; my boyfriend is quite simply very large. I am unable to perform oral sex except for the first couple of inches due to the girth, and vaginal sex is not totally satisfying for him because he is too long and cannot fully penetrate without causing me significant pain. I've seen my doctor, and am reassured that there is physically nothing wrong with me — no infections or scarring, but am finding it difficult to come up with a solution. Any suggestions?


Is there a connection between soy products and male impotence?

I once read an article stating the soy products (espcially soy milk) can lead to impotence within males if taken to a high degree. I go through random bouts in my life where I cut out cow milk completely and drink just soy milk for long periods of time (not because I'm lactose intolerant but for argued health benefits). I'm just wondering whether drinking strictly soy milk every day (at least 3 10-oz. glasses for me) is overkill.


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!!
