Hi ladies

Please don’t judge me I just want to get all I can out of our intercourse! Anyway after my husband and I are finished I feel like an extremely about of semen comes out of me, is this normal ? I expect obviously a little to come out but not this much, and going for a few hours! Do I literally have to lay there with my legs up or am I being silly? I’ve be on birth control for 12 years and I’m just not sure what I should be expecting for how long it’ll take us to conceive
