Hi. My boyfriend (21M) and I (23M) have been together for a year. He is a pure top and I bottom for him. We've talked about him bottoming. Last weekend, we were at my place and to my surprise, he asked me to finger him and eventually, try to put it in. I tried to be as gentle as possible as it was my first time. However, I had a hard time putting it in when we were in a missionary position. My dick curves downwards and is bent slightly to the left. When we were in a doggystyle, I was able to put it in but only after quite some time. As it was his first time and we're both exploring, we did enjoy the moment. So my question is, what's the best position for me to go in easily and for him to have a good time?
