When guys aren’t hard down there...

Ummm so recently hooked up with a guy this past Sunday and for some reason he couldn’t stay hard despite him really ravishing my body.. ummm playing with my breasts. Sucking it and touching me. I gave him blow jobs and squeezed his balls as asked. While he jerked off. But when it came to actual sex. I felt it for moment then he went soft? Maybe not enough foreplay. Basically he kissed me and took off his clothes as well as mine. Sooo ehhh
