Is it normal to be really turned on by seeing cum squirt?

Ok, the title pretty much asks it but I'll be a little more specific here. 1st some backround about me specific to this subject. I was exposed to pornography at a young age 7-8 y/o. My friend's father that lived next door had Playboy,Penthouse in the open so that was my 1st exposure to porn. From that point fwd I was facinated with it. Around 7th-8th grade another school friend got his hands on a porno tape and that really peaked my interest. In that time I had discovered maturbation etc. So I guess its safe to say I was exposed at a fairly young age to porno. As I got older and was able to purchase and view porno freely I found that I gravitated to cumshot compilation videos. And then one day I found a video that was just one cumshot after another, no sex scene just the cumshots and I thought this is my favorite video of all. It turned me on so much to see cumshot after cumshot. And then I saw cumshots where it was really squirting far! (not fakes real cumshots) and I discovered that seeing cum squirting out of a cock and hearing the guy grunt with each squirt really drove me wild. Now, I'm not gay and I have no prob with people who are gay so its not like I'm desperatley tryng to deny that I am. I honestly have no desire to have any type of relationship with a male at all sexual or romantic. I have however "experemented" oral and mutual jerking no anal or anything like that and that also happened at a faily early age. I have in recent years done some mutual jerking but thats all. I am divorced but am living with my current girlfriend. There is occation where i would be open to certain stuff with a guy but rarely act on it. I don't find guys sexually attractive. Gay porn cumshots would do nothing for me. I guess I'm wondering am I bi,just a really horny sexual person or what? Male cumshots though in straight porn really drive me wild. I welcome your thoughts and opinions.
