more lubricacation is probably your main problem

or he could be irritateing your cervix

i hsve that problem too but it doesnt seem to be lack of lube...the bone down there dont have alot of padding so when he is thrustin or fingering me i get bruised do its like i rode a bike for a couple hours... at least that is what it is for me... and i hovent been able to fix it yet... except to just not have him put pressure there but it is difficult...
