I am not actually worried but simply curious. When petting with my boyfriend and getting in contact with his sperm, my skin turns slightly red where his cum touches me. Am I allergic, or is there perhaps any other explanation? I am 24 years old and female.

Recently I bought a sun protection cream from a health food store. The cream claims to provide sun protection (it's labeled SPF 15) by a plant complex made of PABA, willow bark extract, myrtle and myrtus leaf extract. It says that myrtle and myrtus leaf help protect from both UVA and UVB.

My questions are as follows:

1) Can this PABA complex provide the sun protection it claims (SPF 15 for both UVA and UVB rays)? The reason I am asking this is because until now I had only heard of sun protection by titanium dioxide or chemicals like octyl mexaoxycinnamate (did I get it right?). So I am curious to find out.

2) I notice a slight burning sensation in my eyes after I apply the product on my face. Is it true that PABA is a common irritant? (Since I notice many products proudly claiming PABA-free I wonder if it's really not good for you.)

Please help. I hope this question falls within your realm of expertise. After all, you are the 'know it all' around here, aren't you?

Someone told me that ChapStick was addictive and the way I'm going through it, I believe them. Is it truly addictive? Can I get help?

Ever since high school, I've had very oily hair and skin, but it became worse in college. Now I'm in my mid-twenties and have to shampoo my hair about 10 times each day to get it clean. Then by evening it's already oily again. This isn't my scalp trying to moisturize itself after being over cleaned, because I've tried not washing it completely and it's even oilier the next day.

Are there any special shampoos or medications that help reduce oily skin? I've tried some facial products from my dermatologist, but they haven't reduced the oil production. This is an embarrassing problem and limits the overnight activities I can do, like camping or staying with friends.

I've come down with chickenpox. Should I stay home from classes even though 90 percent of adults have already had it and are thus immune? If I take great care washing my hands and avoiding coughing anywhere but into the crook of my arm, will I be reasonably assured of not spreading it?

I have an invisible disability and I'm really getting into disabilities activism. Even in liberal circles ableism is still pretty accepted and this upsets me. However, when I try to educate people around me, it sometimes goes awry. I had one friend get upset when I called her out for using the word "retard." Another got upset when I pointed out that her Facebook post of inspirational people with disabilities (that just showed people with disabilities doing normal things) was a little offensive and tried to tell her about "inspiration porn." I get that using the word "retard" is normal as is "inspiration porn." I just don't think it should be.

I know my friends are caring, socially conscious people. I expect people to be a little upset, but ultimately I would also expect them respect the fact that it's really not OK to objectify people with disabilities in the way that inspiration porn and the use of words like "retard" do. What I want to know is how do I point out that people are expressing a harmful social bias, without having them get so upset that they write me off as an over sensitive concern troll?

Is there any cure for itching when I wear wool clothes? In the winter time, I love to wear my wool pants and sweaters, but they make me itch. I've tried wearing pantyhose underneath, but it doesn't work.

Help.
