Just not that interested in sex..

Hey guys (and gals if you're reading),So, I've been thinking about this for a while now but I'm pretty new to the reddit bandwagon so I thought I might ask and see what happens.Long story short is that I'm just not that interested in sex. The idea turns me on and I masturbate most days, but I'm not that keen on actually shagging. I'm not overly experienced with sex, mainly cause I try to avoid it, or I will turn it down last minute.So therein lies my predicament: am I only not keen for sex because I'm not experienced?When I fantasise I'm the bottom, yet I've only ever bottomed a couple of times and it's never been great. Should I just grin and bear it and hope that one day I'll be more inclined to enjoy sex as a whole?Should I simply not have sex? The only time I ever look for sex is if I'm drunk. Never sober. I've had sex once this year.If I'm sober and someone instigates sex, I will internally freak out and then not get hard. So if that happens I generally run and then the issue in itself gets worse.So people of reddit, what are your thoughts? What are your experiences?
