Because I've seen how most of women react when they see some news about LL and their comments are that the ones who do it are pathetic, insecure etc.
I don't think what you're seeing online is indicative of anything. There are a lot of miserable, unhappy people out there who have nothing better to do then spread their misery. If you go by that, there are a lot of other things you should avoid doing because "people online think it's pathetic". It's like if you only watch the news and never step outside you'll think that you're going to get shot as soon as you leave your house. Fortunately, that's not the case.
Personally, honesty is very important for me, so I'm not going to hide it. I do understand there is a "risk" that I tell someone and they won't be interested in me anymore. I'm ok with that. If someone feels that way - I rather know it then don't, and we can go our separate ways. I believe the right person will be ok with it, and if you think literally every woman on earth won't - then I do think you're very delusional.
I'm only beginning my distraction phase right now, and not in a relationship, so I can't comment on relationship specific scenarios. What I can say is that I've told a bunch of women, both friends who know me for a long time, and also a few women I met post surgery, and as I said the reactions were very supportive.
Just to be clear - I don't think there is anything I can say that will change your mind. That's fine, so I'm not even trying to do that. I just want to establish that your entire view on the topic is completely hypothetical, "backed" by online comments only, which I think are pretty much meaningless.
