me and my boyfriend were having sex you know it was hot and heavy him on top me bottom he starts grabbing my butt fucking me hard going ham... well he sticks his finger in my ass... I'm not a huge fan of it but I just let it go but now that's all I can think about it was such a turn off for me but a HUGE turn on for him should I let him do it again or should I let him know I'm kinda weirded out about it....
