Only had a couple "legit" massages. Got hard during all. I guess she was used to it and ignored, I jerked off getting dressed.

Been sucked off and jerked off his cock in a Walmart dressing room.

In a somewhat similar position, married to an open minded wife.
She and I have liked anal play.
I have fucked as many asses as would let me (all female) and had a couple dildos up my ass and loved all.
I've had some limited expense in M on M (mostly mutual JO and BJ) but always wondered about anal.

Yes. Just want a mutual jack off, trading strokes. If he wants to suck, even better.

As a coincidence, I just changed my sexual preference to "bi....limited".
I'm Happily married (mostly). I don't have a regular JO buddy and have limited M on M experience but I have discovered some time ago I like to jack off a nice cock and like mine to be jacked of.
No hugging, kissing and never tried frotting.
I've been sucked a few times and it was great. I've had a cock in my mouth once, just to see...didn't do anything for me.
To answer your question, each time for me was it just happened.
I have always been open about sexual preferences and in particular my love to masturbate. I don't "push" it but if it comes up, I'll talk about it openly.
I have a gay friend that is also open to discussion (he and I never did anything) but has introduced me a couple times.
One time, I did "advertise" on Craigslist (wife out of town, horney and drinking) and hooked up for a nice jerk off session.

I have a cargo van that I converted to a rudimentary but nice RV. Have used it as you described a couple times

Is it usually just jerking together or do you stoke each other?
"Frotting" maybe?
Does it usually lead to "more" right off the bat....sucking...fucking?
My last "buddy", we started off just jerking off together but led to stroking each other. Eventually some sucking but no cum in our mouths.
After a bunch of years, I may be developing another JO buddy with a younger fellow and times have changed.

Tried it once, just to see, by jerking off with my butt pushed up on the bed headboard and my cock over my mouth.
Later I had a GF that loved to suck and kiss right afterward. It got to be a thing, she would hold my cum in her mouth and give it back in a kiss, I liked it.
I've yet to taste another mans cum.

Just had a shower (my favorite to JO) and it just wouldn't cum.
Still horny and here I am, stoking my cock.....

Being a long time lover of jerking off, I've been "caught" twice. First was in junior high school gym shower, it was embarrassing, I got laughed at. Second was in college dorm communal shower, he was gay (before being gay was OK) and encouraged me to continue. I did and that was the first time I saw another man with a hard cock in person (was kind of a turn on) and we never spoke of it again.
Over the years since, I've tried to set myself up, from time to time, to be "caught" without being accused of being a "flasher".

As a child, as with most other males, I "played" with my cock. I didn't "grow" out of it.
I love to masturbate (I'm doing it now) and as I've gotten older, I don't care who knows.

As I've gotten older, I prefer to think of it as loosing some preconceived notions.
I like having my cock jerked off by someone other than me (male or female).
I have found I like jerking off a nice cock.
If a guy wants to suck me and he's not a jerk, yes, it's happened more that a few times.

That I needed to jerk off so I came here. Now my cock is hard and I'm stroking it....

1. Do you visit this site to start or finish a masturbate session?
2. Is your cock hard or just an "urge" when you "click" on this link?
My answers:
1. Start but sometimes start and finish depending on the posts
2. Just an urge.
Full disclosure, my cock is hard, I am stroking it!

since I'm done with cancer treatments and getting the "drive" back I'm back to the usual once a day.....My cock is getting hard in my hand as I type this
