Is it normal to not be turned on by full blown sex, and just prefer oral?

I know it sounds strange but here is my gig...

I'm a virgin, and I think this might be the reason, but no matter how hard I try I can not get turned on by all out sex. The only thing I been turned on by is oral sex...
I think this might be a problem in future relationships, but is it something I can work on?:confused: Whenever I fantasize about a girl giving me oral I really get excited, though, whenever I fantasize me and a girl having all out sex I just can't get excited. It's kinda the same when I masturbate... I can't watch a girl and a guy doing it... The main reason is because a see a guy too and I can't do that because I am straight and it's very awkward for me. Is this a problem or is this normal for some people?:confused:

I've never gave, nor received, and all I have done is make out...
This might be because I am a virgin I'm not quite sure..
Any advice, suggestions, or whatever would be much appreciated.:o

Alright.:)..

Good to know it wont effect my future or anything...
I really appreciate it Leigh.:cool:
