As mentioned in another post - thought I'd start a new conversation. Personally, I think no. Depends on how he/it is positioned.
Yeah it just depends. I've been sitting on a guys lap and was able to tell he was quite big, it was impossible not to. But that's definitely not the norm...
It varies.. Most the time you can except in my current relationship. First time I sat on his lap I felt him get hard... He felt HUGE. Not the case, average. Not complaining just stating
Well, I'd say (as others have), "It all depends." Is the man in question aroused or not? Is he wearing tight or loose pants? Are they jeans, slacks, sweatpants ... ? Is he wearing boxers, boxer-briefs, briefs beneath ... ? There are a lot of variables that can affect just how accurately (if at all) you can tell a man's size by the Lap Sitting Test. The best way is still (and always will be) reach on down there and get a really good feel of it!
My girth is often is noticeable in my trousers and especially when I wear jeans, and I have caught more than a few women taking a look. One always sticks in my mind because I caught her and made eye contact with her, and she burst out laughing because she knew she'd been sprung. I think it's the same as nice bust, well proportioned hips, nice legs.
Not sure , but this sounds like a great carnival attraction... Set it up right next to the " guess your age" booth.. The fun part for me would be proving them wrong and then winning a stuffed teddy bear.
Just because a woman is on your lap does not necessarily mean that the man will be fully hard. So, it may tend to distort the numbers, so to speak. Since there are just as many 'grower's' as 'shower's'. It can perhaps give you some sort of indication, I suppose. Depending on the specifics of the situation.
I find this happens a lot, it seems like when penises are hard inside pants they tend to seem a lot bigger for some reason, maybe just the material or position they are in.
