embarrassing

Hey guys, today me and a partner tried having sex in a car and he couldn’t get it in. literally just the tip would reach. We have never tried having sex before. we’ve just been doing literally everything else for the past year. he said its better to not have sex because we’re good friends and co workers. but anyway, we tried to today and he couldnt get past the tip. he blamed the car being too small but i’ve had other experiences in the same car or even less space, anywho. i just dont know how to feel about it. after we tried he got off of me and i just finished him off, and i left home. i dont know if i should be embarrassed or if i should just let it go or how to proceed, i work with him tomorrow. ahh help
