I think it's normal to be aroused regardless

Yeah, that's true.

I guess what I mean is, how do people...I dunno..."focus" when drawing porn. I dunno if I'm wording it right. Like I'm just not good at fully focusing on the drawing if I'm aroused.

I would offer ideas to help with that but I guess it would lead to a sticky defeat regardless

Pfft...I dunno. I'm sure people have tips on what I could do that might help. Ya never know. ^^;

Other then require me being tied up under a drawing desk

*headdesk*

First tying up wouldn't be required.

Second, if I couldn't concentrate before I certainly would be able to concentrate then. XD

I saw it on an artpic once XD

It over all depends on what your stimuli of choice are, when it comes to you pleasuring yourself. My stimulus for example is imaging/visualising settings/situations, so of course I have to face arousal fairly early in the work process, but won't be bothered by it anymore by the time I get to clean up my lines and begin colourisation. Others may have to face arousal during these later phases because perhaps a certain shade of pink on the lower belly or a certain level of body detail provides them with an optical stimulus they are more inclined to follow than the route of abstract of imagination.

Arousal may lessen with time because eventually the topics you draw becomes trivial enough for you, just like frequent nudists no longer consciously noticing the nudity of themselves and other nudists around them.
You may also consider to act on your arousal and then use the precious cooldown time after getting yourself off to get the arousing aspects of your work finished, so you can focus later on those important aspects you don't find as arousing. Just don't despise or belittle yourself over feeling aroused during your work process because that won't help with making it a trivial thing for yourself and is utterly unnecessary.

Of course for all of this I assume, that one is drawing for themselves, but lastly there is also the situation of you drawing pornography of things you have no qualms with drawing but which don't do anything for you, other than paying your bills or getting you appreciation and praise from others. I'm not certain, if one's arousal is a problem in these instances.

Sometimes when I'm watching public streams of artists abruptly switching from general to mature audiences, I also notice a certain detachment of the artist from the topic in order to remove the awkward seriousness of the matter and trivialising things with the undeniable fact that all genitalia are simply hilarious in their designs.

Stimuli for me is fairly similar to what you described. Usually I'm more aroused in the sketch phase since I've got to visualize how characters are posed, expressions, etc. and it's lessened by time I get around to line art and color.

I don't despise myself (for this anyways) or anything...I just find it to be a little annoying when I'm trying to work on stuff. I usually resort to acting on it just so I can focus for a little bit, but my "cool down" time ends up being pretty short...

Like when it comes to what sort of porn I will draw, it usually ends up being stuff that generally interests me or else I just have no want to even draw it (usually 'cause I just find the subject matter uncomfortable or something). So even if it is a commission of sorts, there's a good chance I'll get aroused from it.

I guess I hadn't really picked up on that in streams. Mostly due to never having seen a stream where a person just switches from doing clean work to porn. To me, people just seem to talk about whatever while the artist just keeps working (possibly I'm missing out on a lot since I never have the volume of a stream on).

I very rarely get aroused while drawing erotic things. Usually it's during the sketch phase as past that I'm too zoomed in to even see the whole picture. And even then, the rare times I get aroused it goes away pretty quickly. To be honest even if I was aroused the whole time I don't think I'd have trouble focusing. Some people act like they absolutely must get off if they get aroused but I've never had that issue. 99% of the time I'm too annoyed by flaws in the picture I'm trying to fix to be aroused, anyway.

Usually, if I'm aroused? It's when I'm thinking up the idea before I go to draw it.

Yeah, mostly for me it's during the sketch or the whole thinking up the idea. But for me it doesn't go away quickly and I do tend to not be able to focus on drawing whatever it is I'm drawing.

If I ever get annoyed by the flaws I see in what I'm drawing, I just keep scrapping the sketch until I eventually come up with something I like. Or I walk away from it and work on something else. Minor "flaws" don't bother me so much anymore. Like flaws have to be really glaring to bother me that badly (like really screwed up anatomy...or hands...hands always bother me).

Hands were invented by the devil to destroy artists.

It purely depends on if you are also into that kind of stuff. I have drawn a lot of things in the past that I really dont care for and that was never an issue for me.

True.

I avoid drawing anything I'm not interested in just on the basis of if it makes me uncomfortable I don't want to draw it or I'll get through this art quicker if it's something I like.
