above all, dafydd isn't dominant and likely won't ever be, even if his partner wants him to be, because he's afraid of causing who he's with harm, whether it be emotional or physical harm. he may be "dominant" until the moment of penetration, since he's far more confident with foreplay and especially oral sex, where he'll then relinquish all control. positions where his partner is on top, such as riding, are preferrable, as are positions where he's able to see his partner's face if he's on top. this is something he prefers regardless โ he doesn't ever have a desire to be entirely dominating โ but it reassures him when his partner who's being penetrated is in control and that he's able to read their body language and facial expressions.
if he's being penetrated by a man in particular, he also prefers to be able to see their face, particularly if they're being especially dominating โ which is something he has to be eased into, meaning it can't and won't be his first sexual experience with someone unless he's using sex as a form of self harm. there's a comfort in reclaiming sex as a whole, but especially sex in which he's the receiver. he had a partner who he had consensual sex with in this way, and he likes it. he enjoys it. but there's shame there that he's still working through and would like to work through.
all of that being said ! his partner's pleasure is of the utmost importance to dafydd. oral king. he checks in on his partner often, whether verbally or physically through squeezing his partner's hand for them to reciprocate. very doting, whether topping or bottoming. though it may embarrass him while bottoming, it's important that he assures his partner, too, that he's enjoying it. so much praise, then, and reassurance. you are NOT experiencing post nut depression with dafydd, he's letting you know how good you are, how good you feel. he doesn't often initiate, but he's more prone to initiate to bottom, and he'll be upfront about it, telling his partner "you can fuck me if you want" / "i want you to fuck me," which is hot ! once dafydd's comfortable, he'll give himself to his partner, and that reclamation of himself, of his body and of his sex, and how much he trusts his partner to give himself to them, is beautiful. and, again, also hot.
