Yesterday I went to a whorehouse and had some troubles with a condom. I used a normal sized condom when I fucked a black woman with a big ass; at first, she gave me a blowjob that feel good (i contracted my cock muscles to pump **** into the shaft and i saw she felt and responded to it), but i noticed i didn't reach max erection because the condom was too tight, specially on the head and mid shaft, where I'm thickest. Then i layed down and she sat on my cock, moaning, and I fucked her hard. When she got tired she got on fours and I did her from behind, she moaning again... It was hard to feel anything but I kept on going, then I fucked her ass, hard at first but than I couldn't keep the erection and had to stop.
My cock size is 6.5" long and 5.7-5.8" (never measured the head but it is a little thicker than the rest) and here's a pic with me using the same condom I used.

Do you think I should buy extra large condoms?
Thanks in advance for the answers!
