This is an anatomy question and I didn’t know any other sub to ask this. Can you always feel when you get a boner? And if so, is the cause always known?

1. I always can feel, at least while awake. Sometime / often it’s known, but sometimes I’m just tired and it’ll happen to pop up.

2. You can always tell if your penis is erect, yes. It feels different. Plus you are having more contact against your clothes or the like.

   No, the cause isn’t always known. Especially if you are younger, full of hormones, you can get an erection from almost anything, or from nothing at all. Even thinking to yourself “oh God, don’t get hard right now, it would be inappropriate” can get you hard.

   Common reasons:

   * you see someone sexually attractive
   * you have sexual thoughts/fantasies
   * you wake up needing to pee
   * you are generally excited/happy about something
   * your penis gets stimulated
   * someone sits in your lap (see: stimulated)
   * you are embarrassed
   * you are angry
   * you are nervous
   * the wind blows in a slightly unusual fashion

3. Yes always aware of a boner and the start of one

4. Yes it’s fucking annoying when you have nowhere to put it

5. Once at the party my friend (that I rly liked in that way) jokingly sat and bent over me (that was so hot). At the moment I thought we are just fooling around, but afterwards another friend told me that I had a visible boner in my jeans. So my answer to the first question is “no”. In most cases you feel it, but sometimes you can get a little distracted 😅.

6. I can always tell right before it happens. And definitely when I have one

7. Yes we can all be aware of it and it’s very embarrassing when it happens in public. One time I fell asleep in a public place for a few minutes I woke up with a raging boner Aka morning wood. Another time was due to a temperature change as strange as it seems

8. Some states of altered consciousness can make it harder to tell. Like being more than half asleep and drunk.

9. yeah it grows and gets heavy lol

10. i mean, i always know if i have one. cant necessarily say that i know why i always get one, but im definitely aware it exists.

11. My fiancé gets random boners when he’s extremely tired which always sucks because we don’t have a fantastic sex life and I’m pregnant and rearing to go 24/7. The days he feels fine or isn’t tired, I’m usually the one with morning sickness or cramping 😭

12. I can always tell for sure, rather it was intentional or not, or if I am half hard or full on erect. I have had some for no reason what so ever and it can happen anywhere sadly, also I can feel the blood inside my penis, especially the throbbing that may or may not come with a super hard on. 75% of the time it’s mainly due to arousal, the other percents are morning wood and random boners.

13. Yep, I’m always aware. But for me the cause is almost always thinking about sex or my wife hitting on me… or me hugging my wife. The only other cause really for me is morning-wood— just waking up with a boner.

14. Maybe a bit too niche, but it’s difficult to feel it in a jacuzzi, because the bubbles already give it an upward motion making it feel a bit like a boner, especially when the bubbles hit the right spot and you think you might get one.. but then when you look down or casually stroke your hands past it, you feel nothing

15. You can always tell for sure. Unless you’re completely passed out sleeping
