I had a petite GF, with a very tight vagina, I had to be very careful while having sex with her, it had to be slow and very gentle, always feel like a turn down no to be able to fuck her really hard, however, looking back... it was a hell of a good time, I was able to last more than an hour, I only needed few minutes to have my dick hard again... and above all I had the hardest orgasms ever... so hard I thought I was going to shit my self... might sound gross... but I haven't had such hard orgasms again...*sight*
