Another case in point; I recently met up with a former girlfriend, who I went out with almost 30 years ago, and who had got back in touch. We arranged to go for a day out, catch up, get lunch etc., and just chat. I was wearing my usual t-shirt, shorts and this time ComfiLon 599's (which are awesome by the way!) in Tan, and deck shoes (which I prefer for driving). We spent the whole day together, drove a couple of hundred miles, and visited lots of places of interest; it was a lovely sunny summer's day. When we got back to mine at the end of the day, we sat in the living room with cups of tea and coffee, and chatted. It was only then that the subject of what work we now do came up, and I told her about the Legwear4Men web site, and indicated my nylon-clad legs. She sat up, looked hard, and said, 'Oh, I didn't even notice.' And that was that; no further interest, and certainly no questioning looks or anything like that. We have chatted a little more about it since then, and she thinks it's great; no problem!
I think it all comes down to confidence; if you are furtive and look preoccupied, people will be suspicious, whereas if you just carry on as normal, no-one will notice, and if they do, they won't care - they will assume there must be some good reason you are wearing them, and leave it at that.
Now, of course, a great deal of that confidence will come from your own perception of yourself in tights, and this is where tights which are made for men come in; I know that I, for one, could never be confident wearing women's tights, because I would know they are women's clothing, and that bothers me, but if they are men's, then I am confident and there is no problem. Sometimes male wearers say, 'Well, no one else knows if the tights you are wearing are men's or women's,' which may be true, but I know, and that makes all the difference in the world - remember the movie Independence Day - 'plausible deniability'!
Another area in which tights for men are important, is in a man's relationship with his wife/gf/SO, who may be dubious about his wearing of what she perceives as a 'female' garment, but is far less likely to be concerned if he wears a patently male garment. After all, there are male and female versions of jeans, t-shirts, polo shirts, etc, which all at some point made the transition from being a 'male' garment to being available for both genders; why not with tights too (which after all, started off as a male item anyway)?
If you haven't already done so, try it; I am sure you will find that no one gives two hoots! Enjoy!
