Is it okay to feel lightheaded and dizzy after physical activity?

1) When I do a 3-mile or 5-mile run, I run for time and try to finish with nothing in the tank. The closer I get to the end, the more I push myself, because I know I don't need to sustain the effort much longer. When I stop running, I suddenly get very light-headed and dizzy. It never happens while I'm running. I walk briskly while I'm warming down, but that doesn't prevent it. Why does this happen? Is it dangerous?

2)  Sometimes after jogging a while, or cycling a great distance, my head begins to spin and I feel as if I'm going to pass out. Is it normal to have feelings like these, and if so, how intense should these feelings be?


Husband into porn and masturbation, but not me

I have been married for 4 years now and my husband is very heavy into pornography. He masturbates on a daily basis and doesn't care to have sex with me. I have talked to him about it and he said that it's an addiction. I told him that it hurts me deeply and I have been tempted to cheat on him. In other words, find someone else. Anyway, what do you suggest? I have tried to interest him more by using sex toys, sexy clothing, oral sex, etc. I am an attractive person and a lot of men flirt with me but I just ignore them. I work out at the gym. I asked my husband if he was interested in someone else and he told me no. He works a lot but when he is at home he just wants to watch TV and sleep.


In the know about nose-blowing

1) You know when you get a cold and you have to blow your nose a lot and it gets all sore from rubbing it over and over again with a Kleenex? Do you know of any kind of cream or something that you can put on your nose to help soothe the soreness caused by frequent nose blowing? Any suggestions would be greatly appreciated.

2) I am a 16 year old girl who isn't very good at blowing her nose. I can blow the air down hard enough, but nobody has ever taught me a good technique for a proper clear-out. What is the best way to hold your nose in the tissue to get a really good nose-blow? How would you recommend I try to blow my nose?


What about emotional abuse?

I notice in your mental health section, you only have info on sexual abuse. What is emotional abuse? I've heard a lot about it lately, but it doesn't seem very real to me. How can simply being called names, or whatever, be as devastating as people say? Short of being threatened with murder, what people say is just words. I can't seem to find very good articles about emotional abuse on the web.


Grapefruit juice and coffee

I've heard that drinking coffee and grapefruit juice at around the same time can extend the effects of caffeine. Is this true? I know that grapefruits can increase the bioavailability of some drugs... what about caffeine? Is this at all dangerous?


Therapy's working, but I don't always feel like going

I've been going to therapy for some time now for general anxiety and obsessive tendencies, since about October last year. My question is do people always want to go to therapy or is normal sometimes to feel like "ugh, I don't feel like going/care to go tomorrow" like if it's more a burden or a... "Nuisance" than anything else. I can confidently say it's been helping me! But why do I feel like that sometimes? Is it normal? Shouldn't I know that I need it. That it's good for me?


Safer sex in hot water

1) Is having sex in the shower that is hot or in a hot tub safe? Someone told me the heat kills the sperm. I thought it sounds dumb but I was just wondering.

2) I have a question about sex in swimming pools and hot tubs. Will the chemicals deteriorate a condom? Also, can spermicide be used in water or will it be washed away? Please answer. Thank you.
