Here's my issue : I penetrated my boyfriend in doggy style because he asked me for it, but he tells me my penis hurts him when he strikes the bottom of his butt. Someone already had this problem ? What can I do for make him feel better ?

Thanks xkneecole anyway. It's really kind from you. =)
Indeed he's new, therefore maybe he's not used to have sex.
Some people say that having sex during a doggy style is the most painful position. But there must be a way to do it without pain since some do it well.
Any other advice ?

Actually I'm doing it with lube already and this is not the problem. That's truly in the bottom.
But I penetrated him with care enough.
But more weird, it is that I penetrated him in other positions and he wasn't injured, wether it was on side or on the backside.

Please ! I didn't create this topic for talking about gay marriage but for doggy style.

Dexter if I follow your opinion ! So the Humans haven't been made to do all other thing than eat, drink and breed himself.
Therefore you are as well as I am a man outside where he should be.
I put everything I want inside my anus, or all other part of my body ! The issue isn't there !!!
You're not supposed posting on this topic to criticize what I'm doing but for answering to my issue ! Thing you're not doing !
