I can get myself off with a dildo and penetrative orgasms are incredible but it's never happened with dick. Hasn't even been close. It doesn't hit the right spot and it doesn't hit it the right way. For me that spot needs fast rubbing like the clit so the imprecise in-out motion of coitus does nothing for me.
Every time I expected pleasure from penetrative sex I was disappointed and frustrated so yeah, it became something I only did it for the guy and was eager to get over with.
But it could be what
>>15047 said. I can't say I've felt true attraction or chemistry towards the guys I've dated. Maybe I would finish easily if I were super into the guy and/or he were good at sex.
