Is reusing water bottles safe?

I started buying bottled water because it seemed to taste better. As an experiment, I tried refilling the empty bottles with tap water and refrigerating them. And I discovered that what I really liked was drinking chilled water out of the bottle. If no one else is using the bottles, how often do I need to wash the bottles out with soap as opposed to just re-filling them?


How can I find support as a gay student in New York?

I'm an undergraduate student from China. And I'm going to the mathematics department with fellowship. I'm really very happy and eager for my future life in Columbia.

I'm now twenty years, but still have no girlfriends. Why? Because I'm a gay student. Sometimes I really feel very sad about that. You see, I'm also an emotional person and I'm eager for love, but I can't. I'd not prefer to make gay friends on Web sites since many of them are lying and I'm afraid to get AIDS. Since I'm very pure, good looking, and excellent in study, some classmates and schoolmates (male) show great affection to me. But I dare not accept it because I'm AFRAID.

Both my parents are professors, but they are very traditional and could not accept that. At the same time, I do not want to hurt them, so I really don't know what to do. I know New York City have a lot of gay students, and it's also such a "free" metropolitan city, so I'm really very glad, but still mixed feeling.

Here I wanna ask you:

(1) Are there a lot of gay students in Columbia University?

(2) Is there any gay club or activity in CU?

(3) What should I do now?

Thanks so much! I've seen your answer to a lot of questions and feel very excellent. Best wishes!


Why does my boyfriend have difficulty orgasming with a condom?

After being on birth control pills for the past two-and-a-half years, I stopped taking them because of side-effects. Since going off the pill, my boyfriend and I have been using condoms with an additional spermicide. The problem is that he is having a difficult time having an orgasm. He says that the condoms do not provide him with enough stimulation to be able to ejaculate. As a result of this dilemma, our sex life has become almost non-existent.

Could it be the type of condoms that we are using? We're using latex condoms. What can we do? Our sex life is riding on this!


Where can I find support as an adult child of an alcoholic?

1) Are there any adult children of alcoholics groups on campus?

2) My father is an alcoholic and I've been told that I should stay away from drinking altogether. I'm a freshman this year and it seems like most of my friends always want to go to keg parties or hang out and drink. Sometimes I drink with them, but then I feel guilty and worried afterwards as I think about my dad. It's hard to avoid alcohol here, but I don't want to follow in my father's footsteps either. Any advice or support you can give would help. Thanks.


How can I stay safe in a homophobic school?

I'm a teenage gal in a great relationship with another girl who goes to my school. We're both out to our parents and some friends, with okay reactions. The problem is, our school is pretty homophobic, and word is getting out that we're dating. My parents worry we might be physically or verbally assaulted at school. My neighbor, who owns guns, has already asked me about it, and I'm scared for our safety. What can two girls in a homophobic suburban school do? We don't have the same support system some college students do. We don't have a GSA and I don't trust any of the school staff much. Please help!


What is proper gym etiquette?

1) When you are at the gym exercising do you need to wipe down each machine that you use even if you are not sweating?

2) I'm looking for some helpful pointers you might have on the subject of health club etiquette (i.e., don't wear perfume because others will leave workout equipment wearing your perfume). I would appreciate anything you have to offer on the subject.


Is it dangerous to hold in number two?

My boyfriend and I have been together for almost three years, and we've lived together for more than one, but I still can't do Number Two when he's in the house. It's not a problem during the week when we both go to our separate jobs, but on the weekends, it's usually just the two of us in the house all day (and night) Saturday and Sunday and if I feel the need to poo, I have to wait until Monday. My question is this — are there any adverse health issues I should be concerned about with waiting to poo? I know that holding your pee can give you bladder infections, but is there a similar issue with Number Two?


Was this a one night stand or more?

My friend and I went to a male strip club last Saturday. One of which caught my eye. I would have chickened out if the guy we were with hadn't gone over to him and brought him back. We talked for a while and then went back to my friend's house — I was so attracted to this guy I could have died. We started to fool around and things got heavy so he went out to the store (CONDOMS, CONDOMS, CONDOMS!!!).

He seemed very sensitive in the way he acted, letting me know that it would go only as far as I wanted it to, afterwards asking me about how I was doing, how I was feeling — he even started cooking the next morning. After breakfast, though, things got a little weird when he expressed that he wanted to see me again and I took his number, but didn't give him mine. Of course, I also told him that I'm living with a guy who I've been going out with, but that I am moving out in the next month — I felt that I'd better be honest...

How seriously should I take this guy? How much of what he told me should I believe? Do you think that this guy just has sex and moves on? I didn't initiate the subject of seeing him again, although I would totally be into that. How should I handle the subject of the guy I live with??? HELP!!!
