Blowjobs😳

Blowjobs aren't all bad, ya know. I like to watch the way my man looks while it's happening, I like to see the way he unfolds and all that. But when he cums I swallow, because 1. Where the hell am I supposed to spit and 2. I just feel like it makes the whole situation less messy and go more smoother. After I swallow I kinda gag though, and sometimes I get a stomach ache, is that weird? I don't understand why, but on a full or empty stomach I get this weird stomach ache. I told him about it and he was cool about it, he told me to stop swallowing and to just chill so I don't feel that way. But it's not that I don't want do that for him, it's just i dont know why my stomach hurts and it's kinda a mood killer unless I'm horny enough to keep going 🙈
