I let other guys watch me masturbate

I (37m) go to the park where other guys frequently park looking for cock basically. I usually feel out the scenery and will either get out and walk around with a little bit of a hard on or open my door. It doesn’t take long to figure out if someone is into it, but unfortunately it’s all been like 60yr old guys with small cocks. I will still pull out my cock or just get completely naked next to my car and stroke until I cum for them. I’m just waiting for a yooguy with a nice cut cock and I’ll probably end up asking if I can stroke his cock and before i know it he would be feeling my throat and ass all the way up. I’ve never played with a cock, but crave it and this dildo isn’t doing the trick anymore.
