I interned somewhere this summer, and I think one of my co-workers has developed a crush on me. Now I'm back at school. He will still text or call every week even though he knows that I have a boyfriend. At first, I enjoyed our conversations, but I'm starting to feel very uneasy about what's going on. I have to admit, I may not be the innocent one either because I try to make pleasant conversation with him, and I really do like talking to him. I don't want to lead him on anymore, but at the same time, I don't want to make him mad because I've accepted a position at the company and I will be working with him again. HELP!

I am having a problem with somebody else's relationship. It's my sister. I love her dearly and I know that she is being beaten by her boyfriend. She is tied to him by the fact that she has a child of six months by him. She doesn't want to come to her family for help. I think that this is largely because she is ashamed of herself and his behavior toward her. I simply cannot "mind my own business" because I am genuinely worried for her safety and the safety of my niece.

Part of me wants her to sort the problem out for herself, but she is so immature and is used to having men do things for her. This has been going on for some time now. What can I do to stop him?

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?

I'm an anxious person. My clinical diagnosis is social anxiety disorder, but I have anxiety in many other situations and a couple of phobias to boot. I've seen therapists on and off for the past 20 years and have been on multiple SSRIs (I am off of anti-anxiety medications currently). I manage my anxiety with plenty of exercise, sleep, and relaxation exercises, but mostly I just accept that this is the way I am. My husband and I are starting a family soon, and my new worry is post-partum depression or anxiety. If I'm already moody, will the hormones and stresses of pregnancy drive me completely crazy? Does having a history of mental illness put me at a greater risk for developing a disorder like post-partum depression? Thanks for your help!

Is it possible to find female PSA, or other types of sexual fluids on another female? For example, if there was a case of women on women rape, could it be possible to find the woman's DNA on the victim? Like when they find semen on victims?
