I believe I am a fairly non judgemental person. My boyfriend loves his own ass and loves me to spank/squeeze it during sex which I like to do as anything that turns him on, turns me on. Excuse me if I sound weird myself however I find it odd that my boyfriend loves me to give him hand/head and even loves to masturbate when he is in doggy position. Basically on knees, leaning forward with ass in the air. He loves me to go from behind. He also loves squatting which he finds pleasurable. He finds it easiest to cum in those positions and of course during sex which is usually him on top but finds it hard to cum laying down on his back if I give him hand/head. He puts it down to gravity, which I do find a bit strange. He's stated before that he has tried other positions aka sitting but it's not as effective and that he can cum quicker squatting. I asked if it's because of his prostate positioning and he said it could be. He also just said that it's easier, doing it in the shower for example. I asked then if he could stand masturbate and he mentioned he balls and thighs feel too tight together and cannot be freed.  The issue is that it is interfering with our sex life. When we first met, he couldn't cum. It was only till after many tries of doing everything to please him, that he could cum inside yet he was still somewhat squatting, just penetrating this time.  I have mentioned to him that in order for him to be able to cum and not be desensitised, he needs to slowly try other positions masturbating so his body also gets used to it.
