Can condoms be used for masturbation? Or is that a waste?

If one masturbates but does not get involved in any other sexual activities, is that person considered to be sexually active?

Here is my situation: My b/f and I had anal sex, and this was not the first time we've done it. But this time was different. After we were done I noticed there was something that kind of just popped out from my bottom. It's like a piece of your skin or muscle or something. I kept trying to push it back in, but it keeps coming back out. It doesnt cause me great pain, but just a little bit of itching sometimes. What is it? What should i do with it? Is it bad? Please let me know. Thank you.

I know this sounds gross, but sometimes when I get turned on, I like to rub my "vaginal area" on a stuffed dog. After it, I feel good, but a few minutes later, some discharge comes out on my underwear. What's going on, and is this safe?

I've always come to this site to either browse through others' problems and compare them to my own and because I've been sexually curious for as long as I can remember. Recently, a guy I've been friends with and I have started to "get to know each other." Last night, this question arose: How exactly do you "suck balls" and what are the benefits? I looked through everyone's questions, and I didn't see this one.

Should a normal man's penis become erect for a certain number of times throughout one day (without any external stimulus)? Or, do these erections occur only while a man is sleeping? I have been masturbating once every day or every other day, and I have noticed that I rarely get any of those spontaneous erections during the day at all. Plus, I have been waking up with no morning erection during the past week. Have I been masturbating too much?
