Touching his penis through his pants..😭

Ok so my boyfriend (19) and I (19) often make out, but I don’t think that either of us are ready to fully have sex yet..

While we were making out in his car one night he started grabbing my upper leg and stroking it while still kissing me. I honestly loved it and things got pretty heated from there.. I’ve also stroked his upper leg before, BUT I’m absolutely clueless about where his dick might be in his pants, so I could “accidentally” touch it during making out and just see how he responds

Like....is it gonna be placed to the side, is it gonna be tucked upwards?? He absolutely doesn’t mind me stroking his leg, so I feel like he would enjoy my hand brushing against his crotch area just as much..

Just please help me in approaching this situation because this honestly stresses me out!!!❤️❤️
