How long should I wait to use Viagra after using poppers?

I know that it is extremely dangerous to mix viagra (or other ED drugs) and poppers (amyl nitrate), and that one should wait for 24 hours after using viagra (to let it get out of your system) before using poppers. My question is what is the waiting period after using poppers before it is safe to use viagra? In other words, how long before the physiological effects of poppers wear off?


How can I tighten my loose vagina?

I have given birth to three children. My last child was delivered without an episiotomy. I have noticed a change in the size of my vagina as a result of this. I am too embarrassed to have sex because I feel too loose. Is this common with multiple childbirths? I am too ashamed to ask anyone this. Please let me know if there is something that can be done to repair my womanhood.


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?


How may having spina bifida affect sex?

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?!


Why do I experience pain after masturbating at night?

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?


Why am I getting nauseous when I'm weightlifting?

It's been about three months since I worked out regularly. I find that lifting for strength (i.e. 80% of max for 5-8 reps) causes me to feel nauseated about 3/4 through the workout sometimes, so that I can't bring myself to finish. I took a weight training course last semester and was affected the same way every once in a while. I warm up, stretch before and after, breath when I lift, drink plenty of water, take care not to eat 1 hour before working out, skip a day between workouts, don't lift more than I can handle (I reduced the weight from what I ended on in the class to a seemingly suitable weight. I got a 98 in the class incidentally). What's going on?
