I do it because I get pleasure from it. The taboo of it is what turns me on a lot: Knowing that the world basically tells you it's wrong, that you shouldn't do this, but I still do it anyway.
With women, I feel like there's still pressure, to be a man, to perform, there's her expectation of why she's having sex with you which usually is not just about sex only.
It's much more relaxing with a man because you're both there for the same mutual reason: cock, pleasure, cum.
Unlike a girl who can lie about enjoying sex, that moment when his head is so big and swollen, his moans so loud and uncontrollable as he violently ejaculates his hot sperm in your mouth, it's the ultimate proof that YOU gave him all of this pleasure and now you're taking it all from him, his pleasure becomes your pleasure as you swallow all of his hot salty life force.
This post is so true for me and probably true for most guys on here that engage in MM sex.
Its interesting about the pressure part you mentioned about being a man when you have sex with a woman. There is, whether you like or not, the pressure is real, sure its not all the times, but its there. You have to please her, turn her on, make her orgasm and then after all that, is the potential fall out, you cant just go about your life like nothing happened you have to be kind and considerate to her.
With MM sex its totally different. As a feminine, passive submissive bottom, I have or feel literally no pressure, mind you I make sure Im ready and prepared to be taken a dick from behind, but I see it as something that turns me on, part of foreplay and part of the excitement of what will come later in the day.
My Top partner has never experienced any pressure or felt pressure to perform and definitely never from me, sure he gives me a nice massage to begin with, but he uses that time to relax, fondle and grope me where ever he so pleases him. Im already excited from the thought of the act itself, so the massage and foreplay is just so much bonus its mutually beneficial to both of us.
The reasons are mutual for MM sex, as you said it is pure pleasure, oral, anal and cum. Once those pleasures are tasted and savoured and had, we both move on with our lives. With a woman its complicated, sure there are times when you can just have great meaningless sex, but generally speaking there is always an underlying reason as to the reasons why and expectations of being considerate and not making her feel like an object. With a guy, well for me at least, I have zero expectations and the thought of being treated as a sex object is a turn on. We wont contact each other till the nex time we want sex, try doing that with a woman and see how long it lasts for most guys.
The enjoyment part too, is anothe signicant difference too. A guy cant lie, his moans, groans and cumming is proof and validation generally speaking that you have satisfied him completely. With a woman, you have no 100% definitive idea that she has orgasmed or had a good time.
