OK, let's look at a couple of these. I'm not a doctor, but here's my opinion:

I have been on sertraline (anti-anxiety) since last May and it has markedly reduced my libido and this annoyed me but now I am coming off the tablets (under medical supervision) and my sex drive is coming back to what it was which I am happy about.
Your posts over the last few days suggested to me that you may be feeling anxious. I'd imagine your doctors have replaced sertraline with something else... if not, you might want tell them you're feeling anxious again and get them to look at it. Incidentally, withdrawal from sertraline can make your symptoms worse, especially if you're coming off it after having been on it for longer than 6 months - so please report this to your doctor straight away.

Earlier I thought about how my life would be different if I was born female and I think that I would probably be skinnier and I would model my look on celebrities (e.g. Cheryl Cole), I think I would have had similar interests but I would probably be into make-up and other female things. I'd also enjoy the attention from guys and having drinks bought for me and stuff and I would like to show off my body (not in a naked way lol)
Many people wonder what life would be like if they'd been born the opposite sex, or a different race, or a different nationality, or in a different historical period, or whatever. All sorts of people like getting attention and showing off their bodies. The overwhelming majority of them are not trans. Anyway, who's to say you're not allowed to experiment with 'make-up and other female things?'. The 1980s were pretty much dedicated to guys doing exactly that.

I have also noticed that I only seem to worry about my penis when it is cold and it shrinks and when I am in tight clothing down below. Could I have been mistaking that for gender dysphoria since worrying I was trans? Maybe, maybe not. When I think about trans I tend to think about that area more but before I worried I was trans I didn't worry about it.
It sounds like you prefer your physical characteristics to be typically male. Which would probably make you cisgendered. It also sounds like you're self-conscious of an obvious bulge in tight clothing. Which would make you human.

I'm also happy when people compliment the size of my penis (but I guess that maybe pre-ops or pre-pre-ops could be happy when told that anyway so this may not be an indicator)
I don't feel discomfort when peopel refer to me as male.
Trust me, most people with gender dysphoria would feel absolutely awful whenever someone points out our (original) primary or secondary sexual characteristics. If you like yours and are perfectly comfortable with being referred to as male, you probably don't have gender dysphoria.

I do get annoyed in clubs when they say 'ladies shout out' but they don't always ask the men to shout out but this is only in certain clubs.
Just from that quote you sound like you identify as a man. Otherwise you'd just want to shout out with all the other ladies.
Either that, or you're just annoyed about sexist DJs.

Also I like urinating standing up. However, when I was around 8 or 9 I used to sit down to urinate but I felt more normal about it when Richard from Richard and Judy said he did it too because he thought it was more humane.
Lots of guys urinate sitting down. Lots urinate standing up. Some urinate standing up in public, but sitting down at home. There aren't actually any rules so whatever you prefer to do is fine. It doesn't necessarily mean anything.
Richard Madeley probably said it was 'more humane' because he was less likely to get a beatdown from Judy for leaving the seat up.

Also, when I am listening to songs that I sing along to or relate to, when they use female pronouns I usually change them to male when I think about how they relate to me but maybe this is just denial :S
Which, once again, sounds like you think of yourself as a man. So you appear to identify as male. You see where I'm going here?
