paranoid about pregnancy

so I have kind of a ridiculous fear of getting pregnant. I’ve never actually had sex with a guy, (I’ve given/received oral and fingering etc) but I’m still paranoid that I’m going to get pregnant. I’m dating a guy who I really like and we’ve been messing around. anytime I touch his dick/cum I get so scared that I’m gonna accidentally touch myself or something and then miraculously get pregnant. the thing is, I KNOW THAT THATS NOT HOW IT HAPPENS. so clearly this is an illogical fear but I can’t help but worry anyway. does anyone else feel this way or have any suggestions about how to deal with this? thanks lol
