Cant get rid of the fear of pregnancy.virgin&avoid sex but scared that objects i touch may have sperm&i may transfer to my vagina.cant even shower?

Fears like this: Should be addressed with a therapist. Realistically, you can't get pregnant not even a sexually transmitted disease in the ways you're worrying about. I can't talk you out of this on the web and I'm sure others have offered all kinds of rational (to them)explanations which haven't helped. This is probably a symptom of a more serious psychiatric condition. See a therapist or psychiatrist.

Time for some work: Some people get excessive fears about spiders, some about snakes or rats, some about things like sex/pregnancy.If this is interfering with your life, you need help deciding what has pushed it to this degree of fear.A therapist can help you explore the origins & this can sometimes help you get past it. You may need meds for a while to help but you do need to learn how to cope. Get started.
