Too big or just really good?

So my boyfriend and I have been together almost a year! Love him, life is great, all that cute jazz! When we are making love however I can feel him most times like he is reaching my lower abdomen. I know it doesn’t work like that but sometimes it brings a little discomfort! I don’t want to ruin any of my goodies down there so I’m wondering if anyone knows what I’m talking about?!
