What Are The Chances Of Getting Pregnant With Foreplay?

Doctor, I’m sorry for asking so many question. I’m quite paranoid about this. But, I need some ideas and interpretation from you. A week ago, I making out with my boy friend with clothes on. After that I went home and I went to toilet. I’m not sure that my boy friend’s semen get into my hand or not because we both have our pants and underwear on. Maybe I did touch his private part with the clothing on. But I’m not sure about it. I heard that sperm can’t pass through clothing. However, I touched my private part after i rinse my hand with water in the toilet. After that, I realised that I made a mistake, I should’ve wash my hand with soap. But before I went to toilet I did take my hadbag and my clothing. Can the sperm die when I’m carry my handbag and clothing? Will I get pregnant this way? I’m very depressed about it and I told my boy friend that I won’t go to his house and make out again. He’s also feel bad for how I’m feeling now. Anyway, I would like to thank doctor for being patience in answering my question. Thank you very much.
