>>5341276Dont take this as trolling, but yes, it may be your tiny penis. Big shit is about same width as regular penis, so it is not a problem. When you have fingered her, she have became more relaxed and loose and your tip have helped too.
Also, the trickiest part is to get the tip IN her. That causes the pain. After that the sphincter doesnt need to stretch anymore, so the pain comes from the friction when pushing in without lube. Women feel that the whole ass is going in.
Your woman didnt feel that, so there havent been too much friction. Only reason i can think of is that your tiny penis.
