...I need advice!? I know I will get many weird and offensive comments. but I would really use a good advice. I bought a strap-on and i want to penetrate my boyfriend. He's concerned but he's up for new experiments. I will use plenty of lube but am not sure which is the best (and least painful) position for him?
he is also afraid i will look at him differently afterwards, how can i reassure him that it will only make me appreciate him more?

thanks a lot!
