How do I begin to talk with my children about sex?

I have three young daughters (ages 8, 6, and 3 years), and I know that it is about time to begin teaching them and talking to them about sexual issues. But my mother never talked to me about such things, so I really don't know where to begin. I do need to do it soon, though, because I was molested as a child and I don't want my girls to go through the same thing, you know, thinking they have no one to talk to about such things. Because my Mother never believed me when I told her that someone had molested me, I want my girls to be able to talk to me about anything. But I am very shy and easily embarrassed by certain issues, such as sex. How can I overcome this, and how do I spark a conversation about sex with a six-year-old, what should or shouldn't she know, and how can I explain things so she will understand? Same thing for the three-year-old.


Why do some people gag when someone is vomiting?

Why is it that when a person vomits, it causes others to vomit — even when they don't have an illness causing it? Is this something triggered by the brain or is it something that happens by reflex (survival instinct) for someone to vomit since, perhaps, what the first person was eating may affect the second who vomits as well?


Do cosmetics containing sunscreen provide adequate sun protection?

I was thinking of buying a face powder that says it has an spf of 30. It seems convenient to have a powder sunblock since lotions make my oily face greasy. However, I was wondering if this powder will even be effective as a sunblock since I heard that some moisturizers and other products that advertise an added SPF sometimes don't have a high enough concentration of sunblocking ingredients to make it effective. I would like to know what do you think before I make my purchase.


Why do my bowel movements stink so much?

I am living in a residence hall, and I never realized this until now, but my bowel movements are really smelly. It has gotten to a point where if I don't find a place to do it secretly, it becomes a great source of embarrassment. Could I be eating something that causes my bowel movements to be really smelly?


Is there a cure for inverted nipples?

1) I am a male with inverted nipples.

I was wondering if there is any way without surgery to make them come out. They do sometimes come out when it's cold, but go straight back in. I am not overweight, but I do no sports. Would physical activities help???

2) I have inverted nipples. Is there anything that I can do to make them come out? I think that they are unattractive inverted. I have tried massaging them daily as doctors and magazines have suggested, but they do not stay out. They have only come out a couple of times when my boyfriend has sucked on them. Is there something wrong with them? One doctor said that I might have to get a minor surgical procedure.


Does fear of another sex impact my sexuality?

I am a woman who has always been attracted to other women. Until recently, I was attracted to men as well. Now I am almost exclusively attracted to women... which would be fine, except that I think this attraction has a lot to do with painful experiences I’ve had with men. When I was younger, my father was dominant and somewhat abusive, and my first boyfriend was emotionally manipulative and pressured me to have sex with him. After breaking things off with him, I had a very positive sexual relationship with a woman. Am I a lesbian, or am I a bisexual who is just afraid of men? If the latter is true, is there any way to get over this fear?
