Is it normal that i get aroused with shemale and crossdressing porn

Well, i dont know how you all will react to my issue. But its just that i am in serious need for some credible advice and solution on my problem. Here it goes- I'm a 25 yr old virgin guy. Never had any sexual relationship with anyone,cz since i was kinda boring and shy ,so never really had any girlfriend, but had few passing affairs and that too didnt go beyond kissing and foreplay. I had always been attracted to girls. But before 2 years, i was browsing through some porn sites and came across a shemale and crossdressing site. Before that i never knew that transwomen can be so feminine from all aspects. I also figured out that i used to get really aroused with this porn day by day. If their look, appearance, voice n gesture are really feminine and they have big breasts, then only i used to aroused and jackoff on those porn and i wouldnt mind the dick. As days passed, my arousal became an obsession and i started putting bananas and other stuffs in my arse, sucking these for only 2 reasons. To get an orgasmic pleasure and secondly, i used to imagine those objects as the gorgeous feminine shemales dick. I feel like giving and taking blowjob to and from a hot feminine shemale.But as i said, IF there is even a pinch of manlyness, it used to turb me off. I also realised that the moment when a guy or a girl or any shemale is giving a blowjob to another shemale, that part used to arouse me the most and also when the shemale is giving blowjob as well. I also used to get lured towards big breasts of the shemale. But the arse fucking thing in the videos never really turned me on. I continued watching shemale porn and one day came across a crossdressing porn video where a straight guy was fucking a MTF crossdresser. The CD was really really feminine with long hairs, girly voice and wearing slutty clothes. Another video i saw where 2 feminine CD's were giving and taking blowjob to each other in slutty clothes. I jacked off on the video. I then came across some crossdressing porn stories like 2 CD's in action, a guy sucking off a cd, a CD in gangbang. I realised that i really get lured with this CD porn only on 2 conditions. IF the CD has a feminine appearance, no hairs on body, female voice etc and the most important condition was the CD has to be in slutty outfits like panties, garters, stockings etc...cz i figured out that if the CD is wearing these things in the story or video, then and only then it used to lure me to jack off and when am aroused and want to jackoff, i feel like wearing panties, garter, stockings etc and jackoff. But once the feeling is gone, i really dnt have any fetish in wearing this clothes on a general basis or inside my normal clothes. But when m aroused, i feel like getting or giving a blowjob to a feminine CD. Its just that these slutty outfits gives me arousal.I even did dirty chat with couple of CD's and it aroused me to get a blowjob from them. But as i said..if they have any manly thing..it turns me off. Im really confused about my sexuality and thats why i need valuable feedback from you people. I like girls and want to marry only a girl and have family and kids one day. But i really dont know why am i getting more and more obsessed with shemale and mainly feminine CD Porn. I dnt watch gay porn, cz men dont turn me on. But lately, i have observed that my interest in CD and shemale porn videos and stories have increased like anything and interest in straight porn have decreased. I really dont know what you all will think. But please dont pass any negative or harsh words, cz i really gathered a lot of courage to share this weirdest problem with you all for help. Kindly tell me is this just a fetish or obsession or a phase or is it because i have never had sex in my life, so its kinda desperation for sex.So, if anyone of you could tell me what is all this and is this normal and if not, what do i need to do to get it fixed, i'll always be thankful to you. Waiting for response friends. Thank you
