Can a gay man have a relationship with a woman and have normal sex life?

Hello everyone! Thank you very much for the time give to read my question.
I am 23 years old who have never had a relationship, nor sex afairs. Since little I knew I was sexually attracted to men. But since I got in my 20s I fell something for a friend of mine who is straight. I know there isnt anything I can do about it but it makes so confused. I want to be with a woman but I am afraid to get into a relationship because I don't think I am manly enough and I can meet the sexual needs she might have. What I mean is, as a gay person, though who have never have experience with both genders, I am afraid I wont be araused enough to please the needs a woman haves. I am more emotionally attached to girls but feel sexually attracted to men. The problem is fall for straight men which have strong masculine character and appereance. When it come to me, no one knows or thinks I am gay and everyone expects me one day to have a girlfriend. I do really wish that to, but I feel so many different things inside my body toward men and I really feel down. I even get depressed by the fact that I might have the chance to have a woman in my life to experience what other guys do and even have a family one day. I know I should first date and experience but it's that I can't find that arausal in woman and it is very hard for me to get into a relationship. It is just that I seek for the perfect soulmate, but it is hard when you cant feel the attraction to woman. Yes, I can say which woman is beautiful and which is not, but only that. My question is: How can I overcome the fear of woman and sex with a woman so I can see for me who really I am. And if so, can I still be with a woman and have normal sex life? How can I start experimenting so I can find myself? Or if do go for experiencing something with a man, is there a possibility not to feel anyhthing about woman and screwing my even slight chance with being with a woman. It is really important for me to know if I can live like this? I have really hard time accepting myself and even start living normally. Thank you in advance!
