How far does my penis go during sex?

My new girlfriend and I had sex for the first time this weekend. Later in the evening, she was curious about something... "Where is that thing going???" she asked. She mentioned that full insertion was painful and she wanted to know what I was hitting, and "how far does it go?" Being admittedly a bit rusty on my knowledge of the anatomy of the female body, I told her that I thought it went no further than the "uvula" (whatever that is), but that I would do a little research, maybe see what I could get off the Net and get back to her.


Can I be physically active while injured?

About five days ago while I was doing step aerobics I stepped down incorrectly and injured my foot. It turns out, after seeing the doctor, that I cracked a bone on the outer side of my foot and will have to wear a boot cast for about four weeks. My question is, since I can no longer do aerobics, what other kinds of exercises can I do to help me lose weight? I already do weights, abs, and any other type of leg exercise that don't involve me standing, but I don't feel that this is enough and since I am prone to gaining weight easily, I really want to do as much as I can but in a way that I don't aggravate my injury or make it worse.


Was it sexual abuse or just childhood exploration?

I am an 18-year-old girl and it is my first year in college. I am also involved in my first physically intimate relationship. At the beginning of the relationship, I was having a lot of problems with feeling sexually aroused and being physical with my boyfriend. It made me cry almost every time. Then, I remembered some experiences involving adult sexual behavior (both physical and conversations over the phone) with my best friend in first and second grade. I had not thought of these experiences in years, and the memories, even now, make me feel sad, scared, and sometimes guilty.

I remember being afraid to see her and being very upset as a child about what we did. I don't remember much, only very small snippets of what happened here and there. I went into therapy at school, and I can be intimate now without crying, but these memories still bother me and I just want to know what to call it. Is this child-on-child sexual abuse, or just little kids exploring?


Does frequent cycling cause reduced sexual sensation for women?

I have started spinning and I absolutely love it. Currently doing it about 3 times per week. My boyfriend says that spinning will cause permanent damage to my female genitalia, such as damaging the nerves, leading to reduced sensitivity and ultimately impeding my enjoyment of sex. I always wear the appropriate padded shorts. Is this true or not?


If someone's sexually adventurous, does that mean they're more likely to cheat?

If my wife is sexually adventurous, does it mean she's more likely to cheat? My wife is slowly opening up to me about how sexually adventurous she wants to be (I'm talking bondage-type stuff), and I'm afraid that maybe she might cheat in the future if her "appetite" isn't met. I haven't voiced any of these concerns, I've been completely supportive of it and actually would be completely ok with doing all of it. I just worry that maybe the adventure-ness might be a sign of promiscuity?
