Your photo does not look obscene, and your penis is obvious, but only if someone is looking for it.
I can't imagine that it would be a problem.
I've said it before. Women have certain curves. Men have certain bulges. It's biology. We all know that they're there.
We men have a bulge down there, and some are bigger than others. Modesty demands that we cover it, and not purposely draw attention to it. But so long as you don't outline it in flashing neon lights, or parade around in a fluorescent micro-thong (only), it shouldn't be a problem among normal, sane people.
