Yes, it's only polite. Just like you would not start flaping your dick in someones face just because they turned you on. You have no right to condition their responses with your emotions.
Is it because you aren't certain if she feels the same way?
Yes, when she starts rubbing her vagina in my face I think it's appropriate to flap my metaphorical dick in hers.
Are you afraid of getting hurt?
No, hurting. It's a selfish thing to do. It's invasive.
Or have you just not had a lot of relationship experience in general and don't know what you're doing?
Yeah this is not about relationship experience, but rather not making the relationship about yourself. Keeping open ended dinamics that allow you to evolve and grow toghether. LEt's take something obvious, like pegging. I don't like pegging, I don't want to do pegging, if I expres that position it gets pinned and if my partner wants to play we need to redefine the whole issue, which is hard because boundaries are usually less vague than the issue of anal penetration. So I let it go, I don't mention it and if the issue comes up and while fucking she sticks a finger in there, I can remove her hand or not according to what I feel like in the moment. We created a new common emotional border based on how I feel, not rationalisations, not abstractisations and so on. Well emotions are about the same. If you process them verbally they are distorted, conversely your partner interprets them. If you act and express them phisically in the moment they are honest representations of your desire, your partner can accept or reject again by procesing in the moment and so you set a new standard, for yourselfs, a honest consensual one.
I'm getting mixed signals from a dude.
Do you feel the same way every day and every time you meet a guy? Then why have standards of consistency from other people?
I don't think we knew how to handle this goodbye.
J'accuse! Awkwardness between friends, that piece of shit. How dare he?
I'm thinking he wanted to ask me if I wanted to join him and his friends the next day, since we didn't get the "head start" he wanted to that night.
He started rubbing his dick, you said ewww, it's 4 a.m. he understood, ewww, don't rub your dick. THen when he asked what are you doing tomorow he was again pointing at his dick and you just responded what you where doing tomorow. That is why mixing friends and fucks you can't be certain what level is the base line for comunication.(hint, the guy won't say no to the "let's fuck" level and the girl will NEVER say no to the friend level)
I'm not sure why he would want to block his feelings. Perhaps because he figures he can't be in a relationship because of his crazy work hours? Or because I already agreed to just fun and he figures my answer is already set in stone. don't know.
see what processing emotions and actions does? see where you are from "why is he rubbing his dick at 4 a.m.". He probably has some crazy rationalization inside his head as well.
Is there anything I can do to make him feel comfortable in letting his guard down?
being a sex puppet. Dude, people react to one another. You can not live like a compliant emotional slave, just because he gets hurt, that is life. Also, you have no idea if you would actually like his emotional diaree, so take it slow, because no diareea is attractive and you open those gates and you turn him down at that point, now that is just cruel. So you better know how to swim.
