Anxiety …pls help

I don’t know if other people deal with this or what? I’ve recently just gotten into a relationship and I have some nights were I touch myself (I don’t do it often because of my problem) but after I do it and I think of something that would usually make me have butterflies it doesn’t. I feel as if so it’s all because of my anxiety that is telling me that once you do it your thoughts are different, if that makes any sense. This has happened before when I have. It has been about four days. I do get butterflies during the day when I think of ‘subject’ but is it a normal thing?

Thanks for any advice !!
