Whether you are a top, bottom or don't mind switching it up - here are some enjoyable penetrative sexual positions for gay men:

Good ol' Missionary performed by the receiver lying on their back with the giver on top, facing them. Some may think it's boring, but it can be very intimate if you keep an open mind.

Doggy style: Getting its name from how dogs do the deed, we are sure you're similar with this one. If not, please free to Google how it's performed!

Side Doggy style / Missionary: This is pretty self-explanatory. Just how missionary is performed, but sideways. For the giver, this position allows greater access to the receiver's chest, penis, face, neck... The list goes on.

Remember that all, some or none or these could work for you and that the oral sex route is also available. Feel free to communicate with your own body and that of your partner to find out what works best for you!
