Yes, it definitely makes a relationship more difficult. We are, at our core, sexual creatures and no matter how emotional and intellectual our relationships are, a good portion of it will be sexual to the average person. I hate to be the bearer of bad news... but, its true. I actually can't fathom a fair situation in which you could be with a sexual person without them feeling incredibly deprived.
That said, right now, its all about you. Don't worry about that. There are plenty of asexual people out there, so, you can easily find love with one of them and lead a fair, complete life with them by your side. So, don't let the fear of being deprived love sway your judgement because you can definitely still find love.
Think really hard about this, but don't let it stress yourself out. Sexuality is sometimes a hard thing to identify and sometimes hard to ignite for a lot of people. I myself can't find the average person arousing. I've very rarely been attracted to a person before I loved them. But once I do... its definitely there. You may or may not be like that.
Sexuality, lack of or not, is best kept in the side of your mind while trying to figure it out. Not the back because you do need to think about it, but just lightly and curiously and without making yourself stressed out. Know that if you are, it will not stop you from finding romantic love. If you aren't, theres nothing wrong with you; lots of people have a hard time finding people attractive (and once you do, its all the more precious).
