crying during sex??

this has happened to me twice now, me and my boyfriend were having sex (not rough- slowly/romantic i guess??) and i looked at him and immediately just started bawling. i love him with all of my heart and obviously the sex was consensual (if anyone asks) and i was just wondering if that's ever happened to anyone. it was almost like a wave of emotions running through me, a very overwhelming (good) feeling being that close to him and it all just hits me. please tell me i'm not crazy and that's happened to other people 😅
