No it doesn't - but we already established that logic is not your strong point.
No,"we" didn't establish it,
you merely asserted it.
If a man does happen to enjoy penetration and would prefer that he didn't enjoy this impulse, he can choose to control his sexual impulses by having treatment to alter his sexual preferences - that's his business.
Or he can presumably simply alter his choices from the menu of sexual expression, can he not?
Given it has been established that gay men are statistically at a higher risk of getting HIV through this type of sex, which is why the NHS ask men who have sex with men to not donate blood for 12 months after sex
... a ban which I assume you may know has been and is widely criticised and faces constant calls for its overturn ...
Moreover, you don't seem to be too clear about exactly what it is you're trying to say here, flip-flopping as you are back and forth between
A man might prefer that he didn't enjoy penetration and
Gay men are statistically higher risk of HIV blah blah blah.
I think it is perfectly reasonable to want to control this impulse.
Doubtless; but I've seen examples of what you consider to be "perfectly reasonable" so I'll not be setting great store by this.
If that means changing your sexuality - that's for the individual to weigh the risks of treatment and decide accordingly. Last time I checked, being gay didn't suddenly turn you into a weak and feeble individual, incapable of making competent decisions related to your health.
No, but it some cases it can make you prey to manipulative and unscrupulous individuals and groups who seek to persuade you that you should be other than you are on the basis of their (the individuals' and groups') ideologies, frequently though not exclusively religious ones.
Except you have no evidence that a gene-based treatment will involve a lot of time and effort. It could be relatively simple - or at least as simple as plastic surgery or an abortion - which people have the freedom to choose without you worrying about the extent of their psychological problems. If people can relatively freely choose to change their physical appearance, including lightening or darkening their skin colour, there is no logical reason to stop them altering their sexuality.
Save that there are abundant cases where the pursuit of plastic surgery is clearly indicative of psychological issues which merit supportive psychotherapy, not yet another two hours under the knife. There is a continuous spectrum between wanting to do something about your sticky-outy ears because you're embarrassed by them and feeling that your leg is so alien to you that you'll drape it across a railway line while the 1832 to Stamford is approaching. The former is deemed to be innocuous and in fact is widespread; the latter is deemed to be indicative of serious mental disturbance which merits intervention, even if that intervention consists of psychotherapy and medication. But there is a continuum between the two and we draw the line at different stages, that's all.
It's their sexuality, it should be up to them to decide if they want to be gay or straight or bi or somewhere in between, rather than have people like you moralising and dictating to them what they do with their bodies.
On the contrary, moralising and dictating is the very opposite of what I'm about. That's what the religios are for, if they're "for" anything that is.
Or they just need you to mind your own business and let them have the freedom to choose their sexuality as easily as they might choose to "correct" a perfectly nice nose or breasts, simply because it pleases them to do it.
Clearly what passes in what you think of as your mind for your branch of libertarianism extends to allowing absolutely anybody to do absolutely anything to themselves without any kind of let or hindrance or even questioning.
Well, says much.
