A little sick after...

So. My husband and I have been together for almost 5 years. He loves when I give him blow jobs... I mean what guy doesn’t, am I right?! Anyway he also enjoys when I swallow.. again which guy doesn’t?!

It’s always given me a bit of a stomach ache after. The past two times about 20 after I need to use the bathroom real quick, if you know what I mean. It’s almost like taking a laxative. Has this or does this happened to anyone else?

Edit: I know the obvious answer is to not swallow. I don’t hate it, I’m simply asking if this happens to anyone else?
