This man has literally no sexual experience, absolutely none. His first friends were Trevor and Sypha best believe he never even got close to the thought of being touched in more than the familiar platonic way
Everything and anything you introduce to Alucard is new for him, your guidance is necessary no matter how nervous he may seem he's always willing to try these kinks and likings of yours. As time goes by he'll even start initiating sexual situations without you creating the first spark, creating new ideas and positions for you two to try out Alucard dives into this part of his relationship with you rather quickly.
For obvious reasons restraining eachother will be held off for a long time until Alucard can have his arms tied together without pure panic flooding over whatever sexual need he had that encouraged him to try again. But other than that the vampiric lover of yours enjoys basically everything, top or bottom, rough or soft, degradation or praise Alucard will drown you in sickenly sweet dedication to have you weak because of him.
A particular liking of his is blood, a absolute privilege it is to gain your trust to even let his fangs against your neck during such a primal time, he'll always keep your feelings in mind until the moment he gets a taste of what he always keeps himself controlled from, delicious enough to make him stop everything and spend the rest of the night in your arms making small punctures along your shoulders just to enjoy the small drops of your blood but no, Alucard would never stop the movements that have you clawing at his back just cause of the amount of ecstasy that spread throughout his skin in that moment. Though a single taste of your blood would certainly be enough to tip him over the edge if he was just a step from coming together with you in sequence
